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-

Photodissociation Dynamics of Phenol [PDF]
The Journal of Physical Chemistry A, 2007 The photodissociation of phenol at 193 and 248 nm was studied using multimass ion-imaging techniques and step-scan time-resolved Fourier-transform spectroscopy. The major dissociation channels at 193 nm include cleavage of the OH bond, elimination of CO, and elimination of H(2)O. Only the former two channels are observed at 248 nm.

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 ...

The Photodissociation of Propynal [PDF]
Berichte der Bunsengesellschaft für physikalische Chemie, 1985 AbstractThe lowest reaction channel on the electronic ground state potential surface of propynal HC CCHO → HC CH + CO as well as its calculated energy barrier have been examined by UV photolysis and by IR multiphoton decomposition.

The photodissociation dynamics of tetrachloroethylene
The Journal of Chemical Physics, 2011We present a direct current slice imaging study of tetrachloroethylene (C2Cl4) photodissociation, probing the resulting ground state Cl (2P3/2) and spin-orbit excited state Cl* (2P1/2) products. We report photofragment images, total translational energy distributions and the product branching ratio of Cl*/Cl following dissociation at 235 and 202 nm ...

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

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)

Photodissociation of Triatomic Hydrogen
Physical Review Letters, 1988The unstable ground-state potential surface of triatomic hydrogen has served as prototype for the development of bimolecular reaction-rate theory, and is still largely territory only of theoretical chemistry. While the ground electronic state of H/sub 3/ is dissociative, electronically excited states of this molecule are tightly bound. These states are

Physical Review A, 2002
We have calculated the photodissociation cross section of NaH through the B 1 ∏ state. We have solved the time-dependent Schrodinger equation by using the Chebyshev-polynomial scheme and Fourier grid Hamiltonian method. We have used four different sets of potential-energy curves for X 1 Σ + and B 1 ∏ states [E. S. Sachs, J. Hinze, and N. H. Sabelli,
