Abstract : The primary goal of the project was to develop theoretical models for describing molecular motions in gases, liquids, and solids, and to apply these models to the analysis of inelastic neutron scattering experiments. Two types of problems are summarized, first the study of molecular rotations and translations in gases and liquids using time correlation functions and kinetic theory, and secondly the analysis of lattice vibrations in molecular solids in terms of phonon dispersion relations and frequency distributions. In both cases emphasis was placed on improving the understanding, at the molecular level, of the dynamical behavior of fluids and solids and on correlating their properties as determined by different experimental techniques.
