Photodissociation Dynamics of Fluorobenzene

Journal of the American Chemical Society, 2003
Photodissociation of both fluorobenzene and d(5)-fluorobenzene at 193 nm under collision-free conditions has been studied in separate experiments using multimass ion imaging techniques. HF and DF eliminations were found to be the major dissociation channels.

Photodissociation of Triatomic Hydrogen

Physical Review Letters, 1988
The 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

Photodissociation Dynamics of Phenol

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.

Trapped ion photodissociation spectroscopy. Photodissociation of p-dichlorobenzene cation

Chemical Physics Letters, 1993
Photodissociation of p-C6H4Cl2 cation stored in a rf ion trap cell was investigated by observing fragment yield spectra in the 312–327 nm region. The C6H+3 generation was found to be induced by the two-photon excitation enhanced with the resonance on the E—X transition of the parent cation.

157nm photodissociation of polyamides

Microelectronic Engineering, 2000
Research for new photoresists for 157nm photolithography requires the investigation of the basic photochemical studies at this wavelength. The parent molecule disintegrates to small fragments, which are flying apart with supersonic speed. Therefore the photodissociation process, could impose serious problems on the optics of the focusing system by ...

Photodissociation of bromochlorobenzenes

Journal of Photochemistry and Photobiology A: Chemistry, 2008
The 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 of tetramethyldioxetane

The Journal of Physical Chemistry, 1978
Abstract : 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)

The photodissociation of H2S: A study of indirect photodissociation

Chemical Physics Letters, 1984
Abstract 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 ...
