The physics of solvent effects on electronic curve crossing processes are currently of great interest due to the importance of these mechanisms in condensed phase reaction dynamics. Picosecond Raman spectroscopy has been used to measure the dynamics of electronic state decay in simple diatomic molecules. It has been found that electronic decay occurs by formation of transient solvent complexes which relax the electronic energy. The rate of energy relaxation is highly dependent on the detailed vibrational structure of the solvent accepting modes. The ability of different solvents to promote electronic curve crossing is correlated with a simple theory.
