Abstract

The ν1 (N.H stretch) fundamental band of HNCCN+ has been observed at around 3450cm−1 by employing the difference-frequency laser system. In addition, a few hot bands are also observed and one of them is assigned to ν1+ν7−ν7(C−C−Nbend) hot band. The specta were observed in a hollow cathode discharge, consisting of approximately 20 mTorr of cyanogen in a buffer of H2, with approximately 10 kHz discharge modulation, and dry-ice cooling. The molecular constants have been determined for both the upper and lower states of both bands. There is good agreement between our constants, and those calculated by Botschwina and Scbald.1
