The photodissociation of H2S: A study of indirect photodissociation
Chemical Physics Letters, 1984Abstract We have performed calculations for the photodissociation of H2S using surfaces constructed to test a model proposed by van Veen et al., in which the dissociation occurs via predissociated levels of the bound 1B1 excited state. Total Franck-Condon factors for the photodissociation and partial Franck-Condon factors for the product vibrational ...

In this paper we present a quantum mechanical model for direct photodissociation and for predissociation of polyatomic molecules in terms of a sequential decay scheme involving multiple coupled continua, where each continuum corresponds to a different internal vibrational state of the fragments.

Photodissociation of tetramethyldioxetane
The Journal of Physical Chemistry, 1978Abstract : Tetramethyldioxetane was excited with a single 10 psec pulse at 264 nm. The resulting acetone fluorescence was observed and the rise time was found to be less than 10 psec. A mechanism accounting for this and previous experimental evidence is proposed. (Author)

Transition moments and energies have been calculated for the X-A, bound to continuum, transition in HgCl. The photodissociation cross section at the peak (∼20 000 cm−1 or 500 nm) is 1.2×10−18 cm2 at 600 K. The laser energy 17 921 cm−1 or 558 nm) for the B-X transition is close to the peak energy, and a significant absorption will result from a buildup ...

Photodissociation of bromochlorobenzenes
Journal of Photochemistry and Photobiology A: Chemistry, 2008The photodissociation kinetics of 2-, 3- and 4-bromochlorobenzene (BrClPh) and bromo-3,5-dichlorobenzene (Br-diClPh) have been studied in a molecular beam following excitation at 270 nm using femtosecond pump-probe spectroscopy. The kinetics and the dissociation dynamics in the BrClPhs were found to resemble the BrFPhs much more than the BrBrPhs. In 2-

The photodissociation of SO2+·
International Journal of Mass Spectrometry and Ion Processes, 1985Abstract The first ion photodissociation study of SO2+· is reported. Unlike CH3I+· which photodissociates from the molecular ion ground state, SO2+· is observed to photopredissociate from the A and B states via the C and D states. The C ← B contribution to the low energy region is assigned and vibrational frequencies of 100, 46.5 and 55.5 meV are ...

Abstract The absorption of photons by Li 2 from the X 1 Σ + g state to the A 1 Σ + u and B 1 Π u states is considered and the mechanisms that lead to dissociation are studied quantitatively. Calculations are reported on the direct predissociation of the b 3 Π u state. The significance of accidental predissociation of the A 1 Σ + u state
