Abstract | Differential IR spectra of gas-phase proteins at room temperature can be obtained by a combination of IR multiphoton dissociation (IRMPD) and FT ion cyclotron resonance mass spectrometry. This new approach yields unique spectra for all-L and singly D-substituted isomers of the protein Trp-cage (see depicted differential spectrum) and thus avoids possible unfolding of proteins during IR irradiation that can affect conventional IRMPD measurements. © 2009 Wiley-VCH Verlag GmbH & Co.
