Inelastic Neutron Scattering from Solid Benzene

Abstract

Neutron scattering spectra from polycrystalline benzene have been obtained at temperatures between 77 and 270°K. These measurements are compared to recent calculations of spectra using a lattice frequency distribution based on optically determined force constants. The results at different temperatures are discussed, and qualitative agreement between calculated and measured cross sections at lower temperatures is obtained.
