High-resolution infrared spectrum of diazirine- d2, D 2CN 2: Rovibrational analysis of the methylene stretching fundamentals

Abstract

The ν 1 and ν 8 (symmetric and asymmetric CD 2 stretchings) fundamental bands of diazirine- d 2 (D 2CN 2) were studied in the region 2180–2430 cm −1 using Fourier transform spectroscopy at Doppler-limited resolution. The rotational and centrifugal distortion constants for the levels v 1 = 1 and v 8 = 1 were obtained from the overall assignment of the rovibrational transitions of these modes which present A- and C-type band contour envelopes, respectively.
