INFRARED SPECTROSCOPIC EVIDENCE FOR THE SPECIES HNC

$^{*}$Present address: National Bureau of Standards, Washington 25, D.C.Author Institution: Mellon InstituteProlonged photolysis of $CH_{2}N_{2}$ in an Ar matrix at $4^{\circ} K$ produces HNC by the photolytic decomposition of the initially-produced $CH_{2} = $NH. Infrared observations on various isotopically substituted species confirm this identification and indicate that HNC is linear
