Abstract
We have produced a supersonic molecular beam of tryptophan by using a combination of thermospray and seeded molecular beam techniques. The neutral molecules in the molecular beam were photoionized and the resulting mass spectrum was observed. The mass spectrum indicates that the molecular beam contains single, neutral tryptophan molecules as well as small clusters of tryptophan with one or several solvent molecules. The wavelength dependence of the resonantly enhanced two-photon ion signal of the tryptophan parent reveals sharp spectral features containing progressions in one or more low frequency vibrations.
