title: Helium droplet infrared spectroscopy of glycine and glycine-water aggregates.
abstract: Infrared absorption spectra of glycine and glycine-water aggregates embedded in superfluid helium nanodroplets were recorded in the frequency range 1000-1450 cm-1. For glycine monomer, absorption bands were observed at 1106 cm-1, 1134 cm-1, and 1389 cm-1. These bands were assigned to the C-OH stretch mode of the glycine conformers I, III and II, respectively. For glycine-water aggregates, we observed two bands at 1209 cm-1and 1410 cm-1which we assign to distinct conformers of glycine-H2O. In all cases, the water is found to preferentially bind to the carboxyl group of the glycine.
