Abstract
A transient absorption spectrum has been observed in the pulsed CO2 la ser photodissociation of CF2Br2. This has been assigned to the interme diate CF2Br 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 CF2Br at 262 nm and its dimerization rate constant are reported.
