Neutron inelastic scattering spectrum and valence force field for benzenetricarbonylchromium

Abstract
The neutron inelastic scattering spectrum of benzenetricarbonylchromium has been measured between 10 and 2000 cm-1. The relative I.N.S. intensities of the internal modes have been computed from published force fields and in view of the disagreements with our experimental data, a new valence force field has been determined which gives excellent matching.
