Subject: Chemistry
Lesson Topic: Proton NMR spectroscopy: principles, interpretation
Learning Objective/s:
  • Describe the principle of proton NMR and the concept of chemical shift.
  • Interpret multiplicity, coupling constants and integration to deduce proton environments.
  • Apply a systematic approach to analyse a ^1H NMR spectrum and propose a molecular structure.
  • Identify common sources of error and pitfalls in A‑Level NMR questions.
Materials Needed:
  • Projector or interactive whiteboard with NMR spectra slides.
  • Handouts containing chemical shift tables and example spectra.
  • Printed NMR spectrum of ethyl acetate (CDCl₃ solvent).
  • Spectrometer simulation software or online NMR viewer.
  • Whiteboard markers and student notebooks.
Introduction:
Begin with a striking image of a complex NMR spectrum and ask students what information they think can be extracted. Recall prior learning on atomic structure and bond polarity, then state that by the end of the lesson they will be able to decode a spectrum to reveal a molecule’s structure.
Lesson Structure:
  1. Do‑now (5'): Quick worksheet on spin states and chemical shift definitions.
  2. Mini‑lecture (10'): Explain spin‑½ nuclei, energy splitting, chemical shift scale, J‑coupling and integration using diagrams.
  3. Guided practice (15'): Walk through the ethyl acetate example step‑by‑step; students fill a data table.
  4. Collaborative activity (10'): Pairs analyse a new unknown spectrum using the 6‑step checklist; teacher provides feedback.
  5. Check for understanding (5'): Whole‑class Kahoot quiz on identifying solvent peaks and multiplicities.
  6. Summary & exit ticket (5'): Students write one key takeaway and one lingering question on a sticky note.
Conclusion:
Recap the systematic approach to NMR interpretation and highlight how integration, multiplicity and chemical shift work together. Collect exit tickets to gauge understanding and assign a short homework task: interpret a provided ^1H NMR spectrum of an unknown organic compound.
