Title:REMPI and double resonance spectroscopy of L-β-homotryptophan in gas phase
Author(s):Kang, Hyuk
Subject(s):Biology, natural substances
Abstract:Resonance enhance multiphoton ionization (REMPI) and UV-UV double resonance spectra of L-$\beta$-homotryptophan (HTrp) was obtained. Hydrochloride salt of HTrp was applied on a lateral surface of a graphite disk, desorbed by 1064 nm nanosecond laser pulses, and subsequently cooled down by expanding gas from a pulsed valve. Formation of neutral HTrp by laser-desorption was confirmed by its mass spectrum. The REMPI spectrum shows several peaks in a UV region similar to that of tryptophan. UV-UV hole-burning spectrum was obtained and compared with quantum mechanical calculation. Based on the experimental and computational results, conformation preference of HTrp is discussed.
