The determination of binding energy is a very important piece of information that an experiment can provide. We have devised a new experimental procedure to measure binding energies for unimolecular (metastable) decay of multiply charged metal-ligand cluster ions in gas phase. The new technique consists in preparing clusters by supersonic expansion, and in generating metal-ligand clusters by pick-up technique. A high resolution double-focusing mass spectrometer having reversed sector geometry is used to obtain mass-analysed ion kinetic energy spectra. The evaporative ensemble sta­tistical model by C. E. Klots is used to analyse the kinetic energy releases and to obtain the corresponding binding energies. Our new experimental method has been applied to measure the binding energy for the loss of one neutral molecule in a unimolecular (metastable) dissociation in H+ (H2O)n, H+ (H2O)n, and H+ (CH3OH)n for n < 30.
