Abstract : After dissociative excitation into the A state the molecular dynamics of the I2 reaction in solution are followed by picosecond transient electronic absorption spectroscopy. The time scale of the transient spectra varies considerably among different solvents. For the same reaction process, observation at higher photon energy gives longer transient spectral times. The results appear consistent with a model in which the major determinant of the observed time scale is due to vibrational (or possibly electronic) decay after recombination and inconsistent with a model in which the time scale is dominated by recombination time.
