Vibration–rotation infrared emission spectrum of hydrogen isocyanide, HNC, at 2.75 µm

Abstract
The infrared emission spectrum of HNC has been recorded using a SISAM interferometer. Excited-state HNC is formed by reaction of nitrogen atoms with methyl bromide in a fast-flow system at 1–3 Torr. The following transitions of HNC are observed near 3640 cm–1: 1000–0000, 1001–0001, 1110–0110 and 1200–0200.
