The photolysis of FN/sub 3/ by an ArF excimer laser was found to yield both excited NF(b) and N/sub 2/(A) photofragments in approximate yields of 5% and 25%, respectively. The photodissociation cross section at 193 nm was determined to be 2.8 x 10/sup -17/ cm/sup 2/ and the absorption spectrum was recorded from 190 to 450 nm. The rates of NF(b) and N/sub 2/(A) quenching by FN/sub 3/ and NO were determined to be 8.7 x 10/sup 5/ and 1.1 x 10/sup 6/ torr/sup -1/s/sup -1/, respectively, and the heat of formation of FN/sub 3/ was found to lie in the range of 120 to 135 kcal/mol. 24 references, 5 figures.
