Popis:	The coherent inelastic response from liquid deuterium in three different thermodynamic states has been measured on a thermal three axis neutron spectrometer. The observed dispersive behaviour has been analyzed using a damped harmonic oscillator model. The momentum transfer dependencies of the renormalized frequencies and damping coefficients are compared and related to the results from correlated density matrix formalism.
