Comments: The UV absorption spectrum and the kinetics of the self combination reaction of the CCl3 radical were studied by flash 
photolysis in the temperature range 253-623 K.
The UV spectrum exhibits a strong unstructured band between 195 and 260 nm with a maximum at 211 ± 2 nm. The absorption cross 
section, measured relative to (HO2), is (CCl3) = (1.45 ± 0.35) × 10-17 cm2 molecule-1 at the maximum.
