A rate theory and its application to liquid state chemical reactions on the picosecond timescale are outlined. A new feature of picosecond reaction dynamics in solution is the strong participation of solvent molecules. They mainly get in the way of an otherwise rapid combination of reactants. The displacement or reorganization of solvent molecules during a reaction may require hundreds or even thousands of picoseconds, particularly when the reactants contain electrical charges. The rate equations presented here include these solvent displacement rates. Solution of the rate equations for light induced reactions are obtained for continuously applied light and for light in the form of picosecond pulses. The former solutions provide quantum yields, while the latter give dynamical information. Numerical input to these solutions show that experiments should be quite sensitive to solvent displacement rates. Apparently overlooked by photochemists is the great sensitivity of quantum yield data to these rate parameters. Comparison of the theoretical results with a few experimental data will be made.
