| Summary: | Title screen The high-resolution infrared spectra of C2HD3 ethylene was analyzed for the first time in the region of 1230–1340 cm where the strong v12 band is located. The 1748 transitions with the maximum values of the upper quantum numbers and were assigned to the v12 band. The 14 transitions have been assigned to the 2v10 band whose appearance is caused by the strong resonance interaction with the v12 one. For description of the assigned transitions (upper ro-vibrational energy levels), the effective Hamiltonian was used which takes resonance interactions between the vibrational state and three other closely located states, and into account. A set of 70 spectroscopic parameters obtained from a weighted least square fit reproduces the initial experimental data (593 upper energy values, 1762 transitions) with the drms= 1.3 cm. Finally, the strengths of 106 ro–vibrational lines of the v12 band were roughly estimated. Режим доступа: по договору с организацией-держателем ресурса |
