Анализ колебательно-вращательного спектра высокого разрешения и решение обратной спектроскопической задачи для системы взаимодействующих состояний v6, v4, v8, v7, и v10 изотополога этилена C2H3D

Abstract

High Resolution Fourier transform infrared spectra of the C2H3D molecule were recorded with Doppler limited resolution in the region of 600 - 1250 cm-1 at room temperature. The measurements were carried out under several different absorption conditions using the Bruker 120 HR spectrometer in Braunschweig Technical University. Five fundamentals v6, v4, v8, v7, and v10 were observed and found to be perturbed by different resonance interactions. About 6000 lines were assigned in the recorded spectrum. They were used then in the weighted fit procedure with the effective Hamiltonian taking into account five strongly interacting states.
