✦ Synopsis

We have measured the Fourier transform spectrum ( FTS ) of two isotopomers of hydrogen cyanide ( H 12 C 14 N and H 12 C 15 N ) from 500 to 10 000 cm 01 . The infrared data have been combined with earlier published microwave and submillimeter-wave measurements. From this analysis new vibration -rotation energy levels and constants are given, based on the observation of a number of new vibrational levels, especially for H 12 C 15 N. The Coriolis interaction involving D£ 3 Å 01, D£ 2 Å 3, and Dl Å {1 has been observed for a great many levels and in some cases the assignments of laser transitions allowed by this interaction are more clearly shown. New vibrationrotation constants are given that allow one to predict the transition wavenumbers for most of the transitions below 10 000 cm 01 with accuracies of about 0.5 cm 01 or better. Values are given for the power series expansion of the l -type resonance constants and for the centrifugal distortion constants, as well as the usual vibrational and rotational constants.

High-resolution measurements have been made on the infrared emission spectrum of H 12 C 14 N, H 12 C 15 N, and H 13 C 14 N at temperatures on the order of 1370 K. The measurements cover the region 400 -850 cm Ϫ1 with a resolution of 0.006 cm Ϫ1 . New room-temperature absorption measurements are also

In this paper we report new measurements on the \(\Delta J=1\) transitions of seven isotopomers of hydrogen cyanide ( \(\mathrm{HCN}\) ) in most of the vibrational states below \(2000 \mathrm{~cm}^{-1}\). These states are \(v_{1} v_{2}^{t} v_{3}=00^{0} 0,01^{1} 0,02^{0,2} 0,03^{1,3} 0\), and \(00^{0

The absorption spectrum of 12 C 2 H 2 has been recorded by intracavity laser absorption spectroscopy (ICLAS) in the spectral region 10 140-10 600 cm -1 , where three absorption bands were previously observed by Fourier transform spectroscopy. Thirteen bands starting from the vibrational ground state
