Comments: In the photodissociation of CF2ClBr, the quantum yields for Cl atom production were measured to 
be 1.03 ± 0.14, 0.27 ± 0.04, and 0.18 ± 0.03, respectively, at 193, 222, and 248 nm, while those for Br atom 
were 1.04 ± 0.13 at 193 nm, 0.86 ± 0.11 at 222 nm, and 0.75 ± 0.13 at 248 nm. 
The CF2 quantum yields in 193 nm photolysis were measured to be 1.15 ± 0.30 for CF2Br2 and 0.91 ± 0.30 for CF2ClBr.
