β¦ Synopsis
Infrared photoisomerization of both trans-and cis-l.Z-dichioroethylene molecules sensitized by SF6 has been observed by using a CO2 laser. The direct infrared photoisomerization has also been observed for the trans molecule. The reaction rate of the sensitized photoisomerization increases by 6 times as compared with the direct process. The dielectric breakdown induced by an intense laser pulse enhances a dissociative reaction_

The photolysis of SOz at 3712 A in the presence of the 1,2-dichloroethylenes has been investigated at 22Β°C. The data are consistent with the SOz( 3B1) photosensitized isomerization of the 1,2-dichloroethylene isomer. A kinetic treatment of the initial quantum yield data was consistent with the forma
A transient absorption spectrum has been observed in the pulsed CO2 laser photodissociation of CFzBrz. This has been assigned to the intermediate CFsBr radical. The spectrum shows a broad band in the region of 220-320 nm with a maximum around 260 nm. The absorption cross section of CFzBr at 262 nm a
## Abstract The multiple photon absorption and decomposition of ethanol irradiated by pulsed 9P18 infrared radiation (1048.7 cm^β1^) from a TEA CO~2~ laser has been studied in the fluence range 15 to 5 J cm^β2^. The absorption crossβsection is pressureβdependent due to rapid collisional rotational
