| heal.abstract | Homogeneous dimers of phenylsilane, formed in a rare-gas seeded supersonic expansion have been studied by laser resonant two-photon ionization combined with a time-of-flight mass spectrometer. The resonant intermediate states are the S-1 (270 nm) and S-2 (210 nm) ones. The ionization of phenylsilane monomer is inefficient at 210 nm whereas phenylsilane homo-dimers are resonantly ionized with high efficiency at this wavelength region. The wavelength dependence of the dimer at S-1 <-- S-0 origin region implies the existence of at least two, almost isoenergetic, dimer conformers in the molecular beam. Photoionization of phenylsilane dimer induces chemical reactions within the dimer. The detected dissociation channels have to do with -SiH3 and -C6H6 loss and proton-transfer. Van der Waals fragmentation (evaporation of a neutral phenylsilane) is also taking place. (C) 1998 Elsevier Science B.V. | en |
