Intracavity CO laser Stark spectroscopy of the ν3 band of carbonyl sulfide

Mid- and Near-Infrared Spectra, Millimeterwave Spectra, and Global Analysis of 16O12C80Se

“…Complementary terms have been introduced in the Hamiltonian in 1991 (30), and an improved version of this analysis has been recently published (31). Details about the analysis can be found in these three papers devoted to OCS, where the classical notation is used denoting the higher stretching fundamental by 3 and the lower one by 1 , the reverse of the notation used in this paper for OCSe.…”

FT Infrared Spectra of FCN from 1200 to 1800 cm−1 and from 2800 to 7000 cm−1 and Global Rovibrational Analysis of the Main Isotopomers

“…(19). Tables 5 and 6 also contain the molecular parameters of the 13 C and 15 N isotopomers, which will be discussed later.…”

“…Such an analysis was first applied to the OCS molecule (18) in 1986. Complementary terms were introduced in the Hamiltonian in 1991 (19), and an improved version of this analysis was recently published (20). Details about the procedures can be found in those references.…”

“…2 Formulas for the diagonal and off-diagonal terms of the energy matrices are the same as for the global analysis of OCS as published in Ref. (19). For the new fourth-order anharmonic resonance, the vibrational and rotational dependencies of the coupling term appeared to be negligible, so that this term is simply given by: …”

“…They concern all vibrational states up to 2400 cm Ϫ1 , and they add 122 accurate measurements to the 46 previous experimental data. The first part of the infrared study (14) covered the 1800 -2800 cm Ϫ1 domain: in addition to the five bands previously reported by Lafferty (5), 45 bands of 19 In the present paper, we present the results of infrared measurements in the regions from 1200 to 1800 cm Ϫ1 and from 2800 to 7000 cm Ϫ1 . Some details given in the previous paper (14) about the spectra and their analysis are not repeated here.…”
