Picosecond Raman Excitation Profile and Transient Absorption Spectrum of S1 Quaterphenyl in Solution
Received28 Apr 1997
Intensity changes in Stokes resonance Raman spectra of photoexcited quaterphenyl are found to result from 17 ps timescale changes in resonance frequency and width and also in Franck-Condon displacements. The 766 cm-1 anti-Stokes band shows a significant hot population which decays on a similar timescale. The results show that population relaxation, vibronic coupling and solvent reorganisation are all significant on this timescale.
