Abstract

Spectroscopy of biomolecules and their complexes, isolated in the gas phase from interactions with solvent, is a quickly developing field that provides benchmarks for calculations of intrinsic three-dimensional structures of these large species. We employ double-resonance photo-fragmentation approach to measure UV and conformer-selective IR spectra of protonated biomolecules, cryogenically cooled in the gas phase.{Boyarkin, 2006 #61}{Stearns, 2007 #261}{Nagornova, 2011 #27}{Nagornova, 2012 #26} Cooling ions to ~10 K greatly suppresses thermal congestion and allowed us to measure vibrationally resolved UV and conformer-specific IR spectra of protonated biomolecules as large as decapeptides and their water complexes.{Nagornova, 2011 #27}{Nagornova, 2012 #26} we currently evaluate limitations of our experimental approach by pushing it towards spectroscopy of protonated proteins.
