Vibrational Spectroscopy with Neutrons
Several neutron techniques are being used to study catalytic systems [I]. We will limit ourselves here to inelastic neutron scattering (INS) which is a method of great potential interest to study vibrational modes of catalysts and of adsorbed molecules. INS is one of the numerous vibrational techniques available for a better understanding of surface phenomena. Each technique has its particular advantages for a given system in terms of spectral domain, resolution, sensitivity and experimental conditions. For example infrared spectroscopy is a very efficient method to detect adsorbed CO (see the contribution by Maugé et al.) but it is much less sensitive to adsorbed hydrogen.
