The photolysis of C/sub 2/N/sub 2/ CICN, and BrCN at 193 nm have been studied with a pulsed molecular beam apparatus to lower the internal rotational and vibrational distributions of the parent molecules. The results of these studies show how the initial internal energies of the ground-state molecules affect the rotational and vibrational distributions of the products. The observed CN distributions produced from BrCN and CICN were insensitive to changes in the original internal energies of the parents, while the rotational and vibrational distributions of the CN fragments produced from C/sub 2/N/sub 2/ photolysis varied weakly with changes in the internal energy distribution of the parent. These observations have been used to describe parts of the dissociative electronically excited potential surface of the C/sub 2/N/sub 2/, CICN, and BrCN molecules.
