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

โฆ Synopsis
Raman spectra of St tnns-stilbcnc
and its deutcrotcd nnalogucs were obscrvcd. Assignments of the three olcfinic vihrations have been made on the basis of the isotopic Crcquency shifts. The St Raman spectrn arc intcrpretcd according to the newly cstablishcd vibrational assignments, which arc different from those proposed previously.
