Abstract

Tryptophan has been complexed with polar and non-polar solvent molecules using supersonic gas expansion techniques. The ensuing complexes were studied by various laser fluorescence methods (laser scanned excitation, dispersed emission, lifetime measurement). Addition of proton donating solvents always results in the appearance of a new band somewhat blueshifted from the bare molecule conformer origin transitions, near 34960 cm-1. This solvent induced band is similar to one induced in tryptamine and probably arises from analogous interactions. Unlike the case of tryptamine, however, other solvent site interaction possibilities bring about additional redshifted solvent bands as well.
