Infrared Spectroscopy of Cationized Arginine in the Gas Phase:  Direct Evidence for the Transition from Nonzwitterionic to Zwitterionic Structure

The gas-phase structures of protonated and alkali metal cationized arginine (Arg) and arginine methyl ester (ArgOMe) are investigated with infrared spectroscopy and ab initio calculations. Infrared spectra, measured in the hydrogen-stretch region, provide compelling evidence that arginine changes fr...
