Quantitative analysis of ro–vibrational spectra of ethylene: Line strengths of the [formula omitted] and [formula omitted] bands of [formula omitted]C[formula omitted]H[formula omitted]D[formula omitted]-cis

Abstract

For the 12C2H2D2-cis molecule a line strength analysis of 1473/400 transitions of the ν12/ν3 bands was performed by the fit of their line shapes with the Hartmann–Tran profile. Ten effective dipole moment parameters (six parameters for the ν12 band and four parameters for the ν3 band) were obtained from the weighted fit which reproduce the initial experimental 1473 transition strengths of the ν12 band with the drms=3.11%. For the very weak ν3 band 400 experimental transitions are reproduced with the drms=7.72%. The results of the analysis are presented as the Supplementary material to this paper.
