摘要：

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, state are also seen in the anti-Stokes spectrum. Some anti-Stokes bands, notably those at 1570, 1240, 1180, 980, 720 and 285 cm(-1), decrease markedly in relative intensity on a approximate to 10 ps timescale, displaying dynamics similar to those observed for the changes in the band position and bandwidth of several features in the Stokes spectrum.
