Lessons for this topic haven’t been written yet. The objectives below show exactly what the syllabus expects, so you can plan with them in the meantime.
What Cambridge says you should be able to do, in our words. Codes are the topic number plus the objective’s position.
Analyse and interpret a proton (¹H) NMR spectrum of a simple molecule to deduce: (a) the different environments of the protons present, using chemical shift values; (b) the relative numbers of each type of proton present, from relative peak areas; (c) the number of equivalent protons on the carbon atom adjacent to the one to which the given proton is attached, from the splitting pattern using the n + 1 rule (limited to singlet, doublet, triplet, quartet and multiplet); (d) the possible structures for the molecule.
Typical proton chemical shift values (relative to TMS = 0) are given in the syllabus Data section.
