Flash photolysis with time-resolved IR detection is used in investigations of the primary photoreactions of chromium, molybdenum, tungsten, manganese, iron, and osmium carbonyl complexes, and of the ensuing transformations of transient products in room temperature solution.The method bridges the gap to spectral data obtained at low temperatures.It provides information which has previously been inaccessible, such as detailed structural information, and kinetic data in cases where the UV-visible absorptions of the species of interest overlap.Finally, excited-state IR spectroscopy has now become feasible for many organic compounds with the most recent instrumental set-up which reaches a time resolution of >=50 ns.
