How we help at each dissertation stage

Common chemistry challenges – and how we fix them

Most marks in chemistry are lost in predictable places. The students we help usually struggle with drawing accurate mechanisms, interpreting spectra and data, and accurate scientific referencing. We tackle each directly: a specialist writer plans the piece against your rubric, grounds it in the scientific method and peer-reviewed evidence, and references it precisely, so the finished model shows exactly the depth examiners reward.

Levels and deadlines we cover

We support chemistry students from first-year undergraduate through to master's and PhD level, matching the depth of analysis and breadth of reading to your year and grade target. Turnaround is flexible: standard timescales for planned work, and short-deadline support when something has crept up on you. Whatever the level, the work is built around your rubric and learning outcomes so it counts where the marks are.

Referencing and academic integrity

Every chemistry dissertation is written from scratch and referenced in Harvard, APA, OSCOLA, MLA or your university house style. We run Turnitin-style and AI-detection checks on all work and supply it as a confidential model to support your own submission, never as something to hand in unchanged. Your details and brief are kept private.

What UK Students Say About Our Chemistry Dissertation Help

★★★★★

My MChem Chemistry dissertation at Oxford investigated asymmetric organocatalysis — developing a chiral phosphoric acid catalyst for the enantioselective Mannich reaction of glycine Schiff bases, achieving 94% ee confirmed by chiral HPLC (Chiralpak IA column). Expert academic support with reaction mechanism proposals, NMR spectral interpretation (1H, 13C, 31P, 2D COSY/HMBC), and writing a mechanistic discussion chapter grounded in current organocatalysis literature was indispensable.

Emily R., MChem Chemistry, University of Oxford
★★★★★

I researched metal-organic frameworks (MOFs) for CO2 capture relevant to UK net-zero targets — synthesising UiO-66 analogues with functionalised linkers using solvothermal methods, characterising porosity by BET nitrogen adsorption and single-crystal XRD, and measuring CO2/N2 selectivity via breakthrough column experiments at 25°C/1 bar. Expert guidance on IUPAC porous materials classification, GCMC computational screening, and situating my results within COP28 carbon capture policy context was outstanding.

James K., MSc Green Chemistry, University of Nottingham
★★★★★

My dissertation at UCL focused on DFT computational chemistry — modelling the mechanism of Pd-catalysed C-H activation using the B3LYP-D3/def2-TZVP level of theory in Gaussian 16, comparing concerted metalation-deprotonation (CMD) versus oxidative addition pathways, and validating against experimental kinetic isotope effects from the group's experimental collaborators. Expert assistance with transition state calculations, IRC pathway analysis, and writing a clear computational methods section was invaluable.

Chemistry experimental write-up best practice: Experimental chapter — use past passive tense ("The reaction was stirred at reflux for 12 h") — do not use first person ("I stirred"); report quantities in mmol and mg — include equivalents and concentration; cite the source of all reagents (Sigma-Aldrich, TCI, Fisher) with purity grade; describe purification method precisely — column chromatography — silica gel — solvent system — Rf values; state compound numbering consistent with schemes in the main text; characterisation data — 1H NMR (CDCl3, 400 MHz) — report as δ (ppm) with multiplicity — s/d/t/q/m/dd/ddd — coupling constants J in Hz — integration — assignment; 13C NMR — δ (ppm) — CDCl3 — 100 MHz; HRMS — found and calculated m/z — adduct [M+H]+; melting point if solid — range, not single value; IR (KBr or ATR) — functional group assignments; optical rotation if chiral — [α]D20. Results chapter — do not re-describe experimental detail already in Experimental; focus on interpretation and significance of results; use schemes and figures liberally — number them sequentially; compare your results quantitatively to the literature — ee vs published values; explain unexpected results rationally using mechanistic reasoning; draw conclusions clearly. Tables of data — show mean ± standard deviation, n, units. Spectral assignment is good practice — assign all NMR peaks to specific protons/carbons in the structure — use numbering on the structure diagram.

Chemistry literature resources: SciFinder-n (Chemical Abstracts Service — CAS — comprehensive — reactions, substances, references — subscription via university library — essential for synthetic chemistry); Reaxys (Elsevier — reaction database — particularly strong for synthetic procedures and experimental data — alternative to SciFinder); Web of Science (Thomson Reuters — citation analysis — Journal Citation Reports for impact factors — good for finding citing papers); Scopus (Elsevier — broad coverage — author search).

UK-specific: Chemistry World (RSC — accessible news); RSC — Royal Society of Chemistry (UK professional body) — open access mandate for UKRI-funded research. Access via your university library Athens/Shibboleth login — SciFinder requires separate registration with your university email.

Chemistry dissertation safety and ethics requirements in UK universities: COSHH assessment (Control of Substances Hazardous to Health Regulations 2002) — complete a COSHH assessment form for every chemical you use — assess exposure routes — inhalation, skin contact, ingestion; specify control measures — fume cupboard, PPE — gloves, goggles, lab coat; MSDS/SDS (Material Safety Data Sheet — now called Safety Data Sheet per GHS) — read before using any unfamiliar reagent — check sections 2 (hazards), 7 (handling), 8 (exposure controls), 13 (disposal); GHS/CLP pictograms — understand skull and crossbones (toxic), flame (flammable), corrosion (corrosive), environment (ecotoxic) symbols; controlled substances — Misuse of Drugs Act 1971 — precursor chemicals — Home Office licence required for certain reagents — check your university EHS list; particularly hazardous reagents at UK universities — HF — emergency treatment knowledge required; peroxide-forming solvents — diethyl ether, THF — check date and test before distilling; cryogenics — liquid nitrogen — asphyxiation risk; UV radiation — photochemical reactions — appropriate eyewear; waste disposal — halogenated solvent waste (separate container) vs non-halogenated — heavy metals — aqueous acid/base — radioactive waste — follow your department EHS guidelines; accident reporting — RIDDOR — Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. Research ethics — if any human or animal samples involved — university ethics committee approval required before starting; GMO work — SACGM compliance; export controls — dual-use research — certain reagents require export licences; always check your department's specific safety rules and get supervisor sign-off on risk assessments before beginning any experimental work.

BSc Chemistry dissertations (year 3 — final year — typically 8,000-12,000 words — includes experimental work or literature-based review project depending on department): scope — a defined, achievable research question within one academic year; experimental project — one or two synthetic targets, a characterisation study, or a computational study; literature review — typically 15-25 selected papers critically reviewed; expected outcomes — a working synthetic protocol or characterisation data with clear interpretation; dissertation structure — standard introduction/experimental/results/discussion/conclusion. MChem Chemistry dissertations (year 4 — integrated master's — Oxford, Cambridge, Imperial, Southampton, Bristol — 10,000-20,000 words plus characterisation data appendix): scope — a genuine research contribution to the group's ongoing research programme; students work alongside PhD students in the research group for a full year; expected to produce results that could contribute to a publication; independence — expected to plan their own experimental programme with guidance; depth — mechanistic understanding and theoretical background expected at publication quality; transferable skills — group meeting presentations, journal club participation. Key differences in marking: BSc markers look for clear scientific communication, methodological understanding, and appropriate interpretation of results within the scope attempted; MChem markers expect depth of mechanistic insight, broader literature contextualisation, and a contribution — however modest — to the field. Supervisor relationship — BSc students follow a prescribed protocol; MChem students are expected to troubleshoot problems, adapt methodology, and exercise independent scientific judgement. Both require full experimental characterisation data in supporting material.

NMR and spectroscopic data presentation in Chemistry dissertations — standard format per RSC and ACS guidelines: 1H NMR: (solvent, frequency MHz) δ ppm: [chemical shift] ([multiplicity], [coupling constant J Hz], [integration H], [assignment]). Example: 1H NMR (CDCl3, 400 MHz) δ 7.32 (d, J = 8.4 Hz, 2H, ArH), 5.12 (s, 1H, CHN), 3.68 (s, 3H, OCH3), 1.28 (t, J = 7.1 Hz, 3H, CH3). 13C NMR: report all carbon signals — (CDCl3, 100 MHz) δ ppm with functional group assignments — quaternary carbons may not appear in DEPT-135 — note this. DEPT-135 — upward CH and CH3, downward CH2, absent C — confirm connectivity. 2D NMR — COSY (H-H coupling — confirm connectivity), HSQC (one-bond 1H-13C correlations), HMBC (2-3 bond 1H-13C — confirm structure — particularly for quaternary carbons); NOESY — through-space — confirm relative stereochemistry — key for diastereomers; report NOESY correlations that confirm stereochemical assignment. Mass spectrometry — HRMS: [ionisation, instrument] calc. for C12H15NO2 [M+H]+ 206.1176, found 206.1174 — always show calculated and found, and the molecular formula and adduct. Low-resolution MS — EI — [M]+ or [M+H]+ — useful supporting data only. IR: (ATR/KBr) νmax cm-1 — report key absorptions — 3300 (broad OH), 1735 (C=O ester), 1600 (C=C aromatic); identify key functional groups. Optical rotation: [α]25D = +45.2 (c 1.0, CHCl3) — include temperature, concentration, solvent. Melting point — mp 135-137 °C — always report range. All primary spectral data should appear as numbered compounds in the Experimental/Supporting Information — include spectra as figures in appendix — label axis with chemical shift/wavenumber and assign all signals in figure caption.
