The infrared spectrum of 12C32S and 12C34S

Vibrational–rotational spectra of 13CS and global multi-isotopologue analysis

“…Ahrens and Winnewisser [10] reported sub-millimeter-wave spectra of 12 C 32 S, 12 C 33 S, 12 C 34 S, 13 C 32 S, 13 C 33 S, 13 C 34 S and 12 C 36 S. The rotational transitions up to J = 23-22 included some of 12 C 32 S (v 6 16), 12 C 33 S (v 6 2), 12 C 34 S (v 6 8), 12 C 36 S (v 6 1), 13 C 32 S (v 6 5), 13 C 33 S (v = 0) and 13 C 34 S (v 6 2) in vibrationally excited states. Kim and Yamamoto [11] observed the J = 1-0 transition in vibrational states up to v = 39, 16, 7, and 9 for 12 C 32 S, 12 C 34 S, 12 C 33 S and 13 C 32 S, respectively; the J = 2-1 transition was observed for 12 C 32 S in vibrational states from 18 to 20. In 1977, Todd [12] reported vibrational-rotational bands v = 2-0 of 12 C 32 S and 12 C 34 S, recorded with a grating spectrometer with resolution 0.045 cm À1 ; 70 spectral lines were reported for 12 C 32 S and 31 for 12 C 34 S. Using a tunable diode-laser spectrometer, Todd and Olson [13] observed 115 vibrational-rotational transitions that were assigned to bands v = 1-0, 2-1, 3-2 and 4-3 of 12 1-0 of 12 C 34 S, 12 C 33 S and 13 C 32 S. Winkel et al [15] observed the Dv = 2 emission bands of 12 C 32 S and 12 C 34 S with v 00 up to 8 for 12 C 32 S. Using a Fourier-transform spectrometer at resolution 0.004 cm À1 , Burkholder et al [16] measured bands v = 1-0 of 12 C 32 S, 12 C 33 S, 12 C 34 S and 13 C 32 S and band 2-1 of 12 C 32 S. Ram et al [17] measured the Dv = 1 emission bands for 12 C 32 S up to v = 9-8 and J 00 up to 113 for band v = 2-1; they observed the emission from samples at high temperatures with a Fourier-transform spectrometer at resolution 0.01 cm À1 . To date, the vibrational-rotational spectra for transitions up to large v and J have been reported for only 12 C 32 S and 12 C 34 S. Here we report the observation of the vibrational-rotational bands of 13 C 32 S up to v = 5-4 using a Fourier-transform spectrometer at resolution 0.010 cm À1 ; we report also a separate observation of the vibrational-rotational bands of 12 C 32 S up to v = 7-6.…”

“…; rotational transitions J = 1-0 up to 11-10 for 12 C 32 S (v 6 20), 12 C 34 S (v 6 7) and 13 C 32 S (v 6 3) by Bogey et al[9]; rotational transitions J = 6-5 up to 23-22 for 12 C 32 S (6 6 v 6 16), 12 C 33 S (v 6 2), 12 C 34 S (v 6 9), 12 C 36 S (v 6 1), 13 C 32 S (v 6 5), 13 C 33 S (v = 0) and 13 C 34 S (v 6 1) by Ahrens and Winnewisser[10], and transitions J = 1-0 for12 C 32 S (v 6 26) and J = 2-1 for 12 C 32 S (v = 18-20) by Kim and Yamamoto [11], excluding transitions J = 1-0 of 12 C 32 S (27 6 v 6 39).…”

“…The molecular constants used in the spectral simulation were taken from refs – . The simulation did not reproduce the observed spectra without taking into account perturbation due mainly to vibronic spin–orbit interaction.…”

Working Group 5: Molecular Spectra

“…The 2-0 vibration-rotation bands of 1 2 C 3 2 S and 1 2 c 3 4 S near 2530 cm -1 have been reported (204) and a high resolution study of the 1-0 bands with a diode laser spectrometer has just been completed (205). A high resolution study of HNC in equilibrium with HCN has been completed by Maki and Sams (206).…”
