Anti-Stokes resonance Raman spectra of S 1 trans-stilbene have been measured for vibrational wavenumbers up to 1570 cm-1. Trans-stilbene in n-hexane was excited at 290-310 nm and probed at 580-620 nm, respectively, with 8 ps resolution. All the dominant bands seen in the Stokes spectrum of the S 1 s
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
Transient resonance Raman spectra of transstilbene in n-hexane have been obtained using two pulsed lasers at 266 and 585 nm. The former was used to pump the molecule to the fust excited singlet state (Sr) and the latter to proble spontaneous Raman scattering in resonance with the S, + Sr electronic
The first application of picosecond polarization spectroscopy to probe gas phase intramolecular relaxation under collision free conditions is reported. This technique is a sensitive probe of molecular rotation and when applied to trans-stilbene vapor at 2OO'C an exponential decay in the anisotropy w
