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
