Multiphoton dissociation experiments in perfluoropropene and difluorochloromethane have been carried out with one or two wavelengths.It is shown that the increase of selectivity induced by a nonresonant radiation is attributable to an enlagement of the unimolecular reaction regime.The behaviour of large and small molecules when irradiated with two IR laser beams is different.Whereas the distinguishability between unimolecular and collisional regimes is enhanced for sufficiently large molecules, it tends to be smoothed in the case of small molecules.
