Investigation of the Spectral Line Intensities of the ν<sub>9</sub> Band of the Trans-Conformer of Ethylene

Abstract

The intensities of 740 vibrational-rotational lines of the ν₉ fundamental band in the IR spectrum of the trans-C₂H₂D₂ molecule are first analyzed. The Hartmann–Tran profile is used to fit the line contour. More than 2700 spectral transitions are assigned using the ground state combination difference method and the isotopic substitution theory. The special features of the spectral line broadening and the influence of the parameters of the Hartmann–Tran line profile on the accuracy of line contour reconstruction are considered.
