Abstract The infrared spectrum of diazirine has been recorded at Doppler resolution with a high informa­tion Fourier transform spectrometer. The ν3 fundamental has been reinvestigated and the overall assignment of the rovibrational transitions has been carried out. From the least-squares analysis a more accurate set of molecular constants including the sextic centrifugal distortion constants has been determined for the level υ3 = 1 and will be reported here. The higher resolution achieved here allowed the assignment of weaker lines and many Q branch transitions. Moreover many blended lines have now been resolved and could be properly assigned.

Measurement And Analysis

The infrared spectrum of CD4 has been recorded between 942 and 1201 cm−1, encompassing the ν2 and ν4 bands. The data have been analysed taking account of the Bζ24 Coriolis coupling term linking the upper states of the two bands. Six hundred seventy-five assigned transitions, reaching a maximum upper state J value of 20 in each band, have been fitted with a standard deviation of 0.013 cm−1 and new values of the molecular constants are reported.

Effective Constants

The spectrum of CO2 has been recorded in the 2 μm region using high resolution Fourier transform spectroscopy. The effective constants have been determined with good accuracy for the (2001, 0401) and (211l, 0511) triads and the 0112–0000 transition. In addition, the vibrational energy of the (3001, 0601)1V level, previously given, has been corrected. The Coriolis resonance, strongly perturbing the (211e1, 051e1)m and (4000, 0800)n levels, has been studied.
