Abstract
A considerable amount of information was collected over recent years about rotational dynamics of the methyl group in molecular crystals by using principally N.M.R. and neutron scattering techniques. This latter method is particularly powerful for the low rotational barrier cases by providing a complete level scheme in a large temperature and pressure range. Combining these results with precise structural data, a good determination of the potential energy function and of the responsible intermolecular forces may be reached, as illustrated recently with the nitromethane study /1–3/.
