Abstract: The vibrational relaxation of the ?4 mode of CH 3NO2 liquid and its molecular dynamics are investigated. Temperature and solvent effects on vibrational dephasing and correlation times are discussed in terms of the adiabatic impact theory to infer that, in the molecular collision, the attractive part of intermolecular potential is explored. The statistical uncorrelation of rotational and vibrational relaxations is experimentally demonstrated.
