Abstract

Coherent wave packet motions in the electronic excited states prepared by impulsive nuclear rearrangements such as electronic transition, internal conversion, and chemical reaction are observed exclusively by ultrafast 35 fs time-resolved spontaneous fluorescence. Direct information on the excited state dynamics, reaction coordinates, and coupling between excited states can be obtained.KeywordsOptical Parametric OscillatorTransient AbsorptionInternal ConversionExcited State Intramolecular Proton TransferTwisted Intramolecular Charge TransferThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
