Abstract
Inclastic scattering of $225 cm^{-1}$ neutrons from liquid benzene has been observed at several angles by time-of-flight techniques. Effects of instrument resolution, multiple scattering, and coherent scattering have been estimated and accounted for, and the resulting incoherent scattering is analyzed in terms of the interpolation model of Yip $et al.^{1}$ for molecular liquids. The model describes intermolecular translations and rotations, and in the present case frequencies in the range from 0 to $100 cm^{-1}$ are considered. Frequencies which are required to fit these data will be compared to those in solid $benzene,^{2}$ and to i.r. and Raman measurements on liquid benzene.
