The spectra of the coherent resonant Stokes Raman scattering of trans-stilbene in an excited electronic state in a solution have been measured with picosecond time resolution/The changes in the spectra produced as a result of a photoinduced reduction of the lifetime of the Sx state reflect the kinetics of the "cooling" of the vibrational subsystem of the excited molecules.
