1 Introduction to NMR
The activity begins with a general description of how NMR works. It
then moves on to the idea of sets of protons being "equivalent" and a
discussion of the features to look for when interpreting NMR spectra.
Finally there is an in depth description of the use of delta values
and how they are derived.
2 Interpreting NMR Spectra
This activity concentrates on the various features of a molecule's
structure which may affect its NMR spectra. This includes:
- The effect of double bonds on equivalence sets.
- Shielding and deshielding.
- Pi electrons.
There is also a discussion of proton counting and significance of the
area of spectra peaks. The activity finishes with the resonance
positions of some common molecule fragments.
3 Coupling
This activity starts with an introduction to the concept of spin-spin
coupling with an emphasis on the effect that this has on NMR spectra.
The activity then discusses coupling constants and the conditions
necessary for protons to couple. Finally the activity covers
heteronuclear NMR with a discussion of the practical problems of
Carbon 13 NMR and the use of proton decoupling.
