| 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. |
