Raman spectra and absolute Raman cross sections have been mcasurcd for tram-stilbcne in cyclohcxane and methanol using 282 and 266 nm excitation, and calculations have been performed to model the Raman Intensities and absorption spectra. The only out-of-plane vibration observed in either solvent is

It IS shown that dramahc charges m excxtation profiles of certain fundamentals of Pt-phthalocyanine upon mking the achloronaphthakne solvent with n-octane, can be rationaked in terms of a solventdependent co&&ration interaction strength between the B and Q electromc states of a solute molecule.
Resonance Raman (RR) spectra were measured for the cation radical of bacteriochlorophyli a in acetone, methanol, dichloromethane and mixed solvents of acetone and methanol. The ring-breathing (C~-C m stretching) frequency of the radical (abbreviated as v~ +) was observed at 1601 cm-i in acetone (for
The sign of the exponent of the Raman cross section in tables 1 and 2 was reported incorrectly. The correct Raman cross sections are in units of 10m8 A'/molecule, not lo\* as published.
## Abstract Resonance Raman spectroscopy was used to probe the effect of solvent polarity on the molecular structure and isomerization dynamics of 4βnitroβ4β²βdimethylaminoazobenzene (DA). In addition, the influence of the polarity and the relaxation behavior of the solvent on the modeβspecific vibr
