Thermal energies of gaseous organic molecules, relevant to unimolecular dissociations of odd-and evenelectron ions, are estimated by ub initio/RRHO and empirical calculations. Thermal energies can be estimated with good accuracy by integration of molar heat capacities obtained from quadratic least-s
Matrix-assisted laser desorption/ionization combined with time-of-รight mass spectrometry (MALDI/TOF-MS) was used for the analysis of low molecular mass compounds. Three classes of molecules were studied : organic acids, salts of oxyanions and amine-based chelating compounds. Mass spectra from sampl
