Abstract

Shank and coworkers have used ultrafast techniques to extend holeburning to the liquid phase, where they have observed the effects of rapid intramolecular relaxation [1]. Recently, there have been predictions that holeburning can also be used to study intermolecular interactions of solvents with the solute electronic states [2-4]. We present the first transient holeburning results attributable to intermolecular interactions. They show that large non-polar interactions can develop much more rapidly than the well-studied dipolar solvation interactions.
