THE HIGH RESOLUTION FT-IR SPECTROSCOPY OF CYANOGEN-DI-N-OXIDE (ONCCNO)

Abstract

The high resolution infrared absorption spectrum of the ONCCNO molecule has been recorded in the gas phase with a Bruker IFS 120 spectrometer at a resolution of $0.003 cm^{-1}$. No previous high resolution spectra have been recorded for this semistable molecule. The fundamental band of the $\upsilon_{4}$ and $\upsilon_{5}$ vibrational modes at $2246 cm^{-1}$ and $1250cm^{-1}$ have been analyzed and the rotational constants have been obtained. The hot bands that involve the low-lying bending modes are currently being analyzed. The ONCCNO molecule is linear or perhaps slightly quasilinear.
