Vibrational energy relaxation of a diatomic solute in a
liquid solvent is investigated by means of Langevin equation for
the vibrator energy with the stochastic power source characterized
by an exponential time correlation function. The memory effects
included via the stochastic power source allow one to explain the
behavior of the mean square energy fluctuations on short and long
time scales that was obtained from molecular dynamics
simulations.
