The reaction of HCN isolated in solid argon with H atoms formed by photolysis or by a discharge leads to the stabilization of a sufficient concentration of H/sub 2/CN for observation of both its vibrational and electronic absorption spectra. Detailed isotopic substitution experiments have led to a vibrational assignment for this species. The analysis of the vibrational data is consistent with a planar molecular structure and with partial triple bond character for the CN bond. The previously reported electronic absorption of H/sub 2/CH have been reproduced, with only a small matrix shift. The appearance of more highly excited members of the electronic band system suggests a tentative assignment of the band structure for H/sub 2/CH-d/sub n/. An infrared absorption that disappears on irradiation of the sample by visible light behaves appropriately for assignment to the CNH bending mode of cis-or trans-HCNH
