AbstractA-band resonance Raman spectra are reported for gas phase 1-iodopropane. The gas phase absorption spectrum and resonance Raman intensities were simulated using time-dependent wavepacket calculations and a simple model in order to extract the A-band short time photodissociation dynamics for the trans and gauche conformers of 1-iodopropane. The gas phase short time dynamics for trans and gauche are very similar to the results obtained from a reanalysis of corresponding solution phase spectra This indicates that solvation has little effect on the A-band short time photodissociation dynamics. However, the electronic dephasing parameters for the gauche conformer increase significantly upon solvation while the trans conformer parameters are almost the same in the gas and solution phases. This suggests that the gauche conformer in the A-band excited electronic state undergoes stronger interaction with the solvent than the trans conformer to give rise to faster electronic dephasing upon solvation for the gauche conformer. © 1999 Taylor & Francis Ltd.
