ICN has been photolyzed at 266.0 nm and 299.4. The collision free rotational distribution of CN(X 2Σ+,υ″ = 0) after photolysis at 266.0 nm consists of three components with "temperatures" of 37,489 and 6134 K. For 299.4 nm photolysis the CN(X 2Σ+) is formed with 91% in υ″ = 0, 6% in υ″ = 1, 3% in υ″ = 2 with apparently Boltzmann rotational distributions characterized by temperatures of 1673, 1971 and 1865 K respectively. Comparisons are made between these and previous results and are shown to be qualitative agreement. We have determined nascent rotational energy distributions for the dissociation of ICN at 266.0 nm and 299.4 nm. The data at 266.0 nm indicate three components in the distribution. Comparisons between these results and earlier work exhibit qualitative agreement. Further theoretical studies of this photodissociation are indicated to untangle some of the discrepancies. In contrast, the photodissociation at 299.4 nm results in clean single Boltzmann rotational temperatures with somewhat higher vibrational energy than observed at 266.0 nm. © 1982.
