The molecular ion signal was found to be missing for both these compounds, and very similar fragmentation patterns were observed.\n Ab initio<\/jats:italic>\n molecular electronic structure calculations were performed to help understand the fragmentation pattern of these molecules in the laser field. The energetics of different dissociation channels in the ground states of [CHCl\n 3<\/jats:sub>\n ]\n \n +\n .<\/jats:bold>\n <\/jats:sup>\n , [CHCl\n 2<\/jats:sub>\n ]\n +<\/jats:sup>\n , [CFCl\n 3<\/jats:sub>\n ]\n \n +\n .<\/jats:bold>\n <\/jats:sup>\n and [CFCl\n 2<\/jats:sub>\n ]\n +<\/jats:sup>\n , as well as neutral CHCl\n 3<\/jats:sub>\n , CHCl\n \n , CFCl\n 3<\/jats:sub>\n and CFCl\n \n systems, were calculated. On comparing theoretical results with experimentally observed ion signals and their relative abundances in TOFMS, it is inferred that these molecules undergo sequential Cl atom elimination followed by photoionization of the fragments. The absence of [CFCl]\n +<\/jats:sup>\n has been interpreted on the basis of resonant \u00c3 state\u2010mediated two\u2010photon absorption by CFCl, and the subsequent prompt photodissociation processes occurring for this state.
