Microscopic solvation environments and ultrafast intermolecular energy transfer kinetics of trans-stilbene were studied in a sodium dodecyl sulfate (SDS) micellar solution and in a dodecane solution. The UV absorption spectrum showed no evidence of aggregate formation in the micellar solution. The a

The experimental results of time-resolved coherent resonance Stokes and anti-Stokes Raman scattering spectroscopy of the excited electronic S, state of tram-stilbene in ethanol are presented. The detected considerable changes in vibrational spectra due to "optical depletion" of the population of the
