Matrix Isolation Studies: Infrared Spectra of Intermediate Species in the Photolysis of Hydrazoic Acid. II

Abstract

Further infrared studies of the photolysis of hydrazoic acid in solid nitrogen at 20°K confirm the spectroscopic detection of unusual molecular species, as postulated earlier. Neither hydrogen bonding nor tautomerism of HN3 can account for the new bands detected. The two most prominent of these, at 1325 and 1290 cm−1, are shifted by a factor near √2 when DN3 is photolyzed. The data tend to confirm the presence of imine radical NH2 but two alternate interpretations, diimide N2H2, or azide amine NH2N3, cannot be eliminated at this time.
