InfraRed Multiple Photon Dissociation (IRMPD) spectroscopy allows obtaining the vibrational signatures of charged species in the gas phase. The assignment of vibrational modes to establish a relationship between a spectrum and a molecular structure is however non trivial and requires extensive molecular modeling. This thesis describes a complete methodology for the calculation of vibrational spectra and its application to peptides attached to a sodium cation. We start with the efficient exploration of the complex conformational space of these systems, using replica-exchange molecular dynamics, in order to select the most likely structures. We have used the polarizable force field AMOEBA for the cation-peptide complexes, and (re)optimized pa...
