Cryogenic Ion Vibrational Spectroscopy of Protonated Valine: Messenger Tag Effects

Author
Abstract

We report the infrared photodissociation spectrum of tagged protonated valine in the range 1000–1900 cm–1, prepared in a cryogenic ion trap. Comparison of experimental results with calculated infrared spectra based on density functional theory shows that the hydroxyl group of the carboxylic acid functionality and the protonated amine group adopt a trans configuration. Nitrogen and methane molecules were used as messenger tags with optimal tagging temperatures of 30 K for N2 and 60 K for CH4.
