We describe in this paper an improved picosecond timescale spectrophotometer. As the accuracy of ultrashort kinetic techniques improves so can the sophistication of the models used to describe the responses of systems to picosecond pulses. No less than with traditional kinetic studies, it is vital in picosecond work to have analytical methods that characterize the species that are incorporated into the models. In our case the analytical method is spectrophotometry.

    Although this is an elementary result there appear to be conceptual difficulties associated with it since erroneous applications of these principles still appear in the literature.Google Scholar
