High Resolution Infrared Spectrum of the ν7+ν8 Band of the Trans-C2H2D2 Molecule

Аннотация

High resolution spectrum of the trans-C₂H₂D₂ molecule is analyzed on the basis of the Ground State Combination Difference method in the region 1450–1650 cm^–1, in which the hybrid ν₇ + ν₈ band is located. The analysis is performed in the framework of the model which takes into account the Coriolis interaction with the ν₈ + ν₁₀ band. The b-type transitions that in their turn, allow more experimental data on the ν₇ + ν₈ band to be obtained, are determined for this band for the first time.
