Infrared multiphoton dissociation (IRMPD) of a molecule with multichannel dissociation pathways has been an important subject for the better understanding of molecular excitation and unimolecular dissociation mechanisms in the gas phase.'a2 We have recently reported the C 0 2 laser-induced MPD of pentafluoroethane (C2HF5). 3 An important feature in the unimolecular dissociation of C2HFS is that two primary dissociation channels with greatly ...
