MOLECULAR SPECTROSCOPY WITH LOW ENERGY NEUTRONS.
Abstract
The information contained in the neutron inelastic scattering spectra of powder or polycrystalline samples obtained by the slow chopper time-of-flight technique is a useful complement of Raman and infrared measurements. In the latter case, a number of symmetry-dependent selection rules govern the interaction and determine the various frequencies observable in the spectra. In the case of incoherent neutron scattering, such selection rules do not apply so that all energy transfers between neutrons and lattice vibrations or rotational and vibrational motions of individual molecules are observed. The technique of 'cold' neutron scattering was applied to the study of several organic molecules. The results of these studies are represented and compared with Raman and infrared measurements.
