Vibrational predissociation in the HCl dimer.
We present results of a combined theoretical and experimental study on the vibrational predissociation of the HCl dimer. On the theoretical side, photodissociation linewidths and product-state distributions for monomer stretch excited states with total angular momentum J=0 were computed, using the Fermi golden rule approximation. The resonances investigated include excitation of the hydrogen bo...
متن کاملVibrational predissociation spectroscopy of Ar-tagged, trisubstituted silyl cations
Vibrational predissociation spectra of the (CH3)2RSi Arn, (R = H and CH3, n = 1 and 2) ions are compared with harmonic calculations to structurally characterize these putative reactive intermediates. Although the vibrational photofragmentation behavior indicates that the Ar–Si bond is quite strong relative to that found in closed shell ions, formation of the Ar adducts is calculated to cause on...
متن کاملSpectrum and vibrational predissociation of the HF dimer. I. Bound and quasibound states
We present full six-dimensional calculations of the bound states of the HF dimer for total angular momentum J50,1 and of the quasibound states for J50 that correspond with vibrational excitation of one of the HF monomers, either the donor or the acceptor in the hydrogen bond. Transition frequencies and rotational constants were calculated for all four molecular symmetry blocks. A contracted dis...
متن کاملSpectrum and vibrational predissociation of the HF dimer. II. Photodissociation cross sections and product state distributions
We study vibrational predissociation of the HF dimer both by a full coupled channels treatment as well as in the Fermi golden rule approximation. Photodissociation cross sections, linewidths, and rotational state distributions are computed for excitations from the ground state with rotational quantum numbers J51, K50 to monomer stretch excited states with J5K50, both for even and odd permutatio...
متن کاملImaging the state-specific vibrational predissociation of the C2H2-NH3 hydrogen-bonded dimer.
The state-to-state vibrational predissociation (VP) dynamics of the hydrogen-bonded ammonia-acetylene dimer were studied following excitation in the asymmetric CH stretch. Velocity map imaging (VMI) and resonance-enhanced multiphoton ionization (REMPI) were used to determine pair-correlated product energy distributions. Following vibrational excitation of the asymmetric CH stretch fundamental, ...
