Conspectus Femtosecond spectroscopy has revealed coherent wave packet motion time
and time again, but the question as to whether these coherences are necessary for reactivity …

▪ Abstract Modern ultrafast spectroscopic techniques provide new opportunities to study
chemical reaction dynamics in liquids and hold the possibility of obtaining much of the same …

The genesis of the exploration of electron transfer (ET) in the condensed phase dates back
to the origins of chemistry in the nineteenth century. In 1808 Humphry Davy observed [1] that …

Directly contrasting ultrafast excited-state dynamics in the gas and liquid phases is crucial to
understanding the influence of complex environments. Previous studies have often relied on …

Rotational coherence spectroscopy (RCS), a time-domain approach to high-resolution
rotational spectroscopy, is becoming increasingly important as a means of obtaining …

Resolving the structural dynamics of bond breaking, bond formation, and solvation is
required for a deeper understanding of solution-phase chemical reactions. In this work, we …

The ultrafast intramolecular proton transfer in the first excited state of 2-(2′-hydroxy-5′-
methylphenyl)-benzotriazole in solution was studied in two-color pump probe experiments …

A framework for understanding impulsively photoinduced vibrational coherent motion on the
ground electronic surface is presented. In particular strong resonant excitation to a directly …

We report a comprehensive study of the UV photolysis of I3− in ethanol solution, using
femtosecond time resolved transient transmission experiments. We interpret our results to …

The theoretical framework for describing solvent effects on solution phase reactions is
summarized. When possible, the results are related to experiments involving geometric …
