Abstract

Supersonic gas expansion techniques can be used to prepare samples of cold gas phase analogs of tryptophan. The excited state origins of different conformers can be selectively laser excited and the fluorescence decays recorded. When possible 1La state effects on emission lifetime are recognized and eliminated. The remaining data set can be appraised in terms of conformer dependent fluorescence quenching due to election transfer.
