摘要：

The collective dynamics of a molecular liquid (methanol) has been analyzed by means of a comparison of thermal neutron, computer simulation and lattice dynamics data. The wavevector dependence of the average excitation frequencies follows a steep curve as a consequence of the increasing importance of inelastic intensities arising from higher lying optical modes for momentum transfers above 0.5 angstrom-1.
