Nature of the products of photolysis and radiolysis of CBr/sub 4/ at 77 K

OSTI ID:5775082
Photolysis and /gamma/-radiolysis of CBr/sub 4/ in different matrices at 77 K in the presence of electron donors were studied spectrophotometrically. The identity of the absorption spectra of the products of photolysis and radiolysis of CBr/sub 4/ and CCl/sub 4/ obtained in the same conditions was demonstrated. It was shown that photolysis and radiolysis of CBr/sub 4/ in the presence of electron donors in any matrices result in the formation of a product with an absorption band at 470-500 nm. The band was assigned to the absorption spectrum of the CBr/sub 3//sup +/ cation in the (CBr/sub 3//sup +//parallel/Br/sup /minus//) ion pair. The most probable mechanism of its formation was proposed.
