There exists, today, many and effective methods of three-dimensional structural characterization of biological compounds in the condensed phase (NMR, X-ray diffraction or circular dichroism). In the last ten years, this field has extended to the gas phase. This work falls in this context and considers the structuring role of Na+ on the ! amino acids Gly and Pro and on oligo-peptides of Gly and Ala, ! by combi ning theoretical calculations and infra-red spectroscopy of gaseous ions by multiphoton dissociation (IRMPD), coupled to mass spectrometry. Experimental IRMPD spectra of the sodiated amino acid complexes, enabled us to identify the exclusive presence of the zwitterionic form in the case of Pro-Na+ and the presence of the non-zwitterion...
