Abstract

We have measured one color multiphoton dissociation/ionization (MPD/MPI) spectra for a series of arene molybdenum tricarbonyls. These experiments measure the relative timescales of multiphoton excitation, intramolecular energy redistribution (IER) and unimolecular dissociation under collision free conditions. The results indicate that IER is accelerated by the presence of low frequency vibrations and by molecular structures and bonding which enable a molecule to remain intact longer during the course of multiphoton excitation. The results for the organomolybdenum molecules are consistent with our earlier results obtained in a similar study of organochromium molecules.
