| Summary: | Заглавие с экрана Present work is a continuation of our extensive high resolution study of ethylene. Ro-vibrational spectrum of the trans-C2H2D2 molecule has been recorded in the region of 1450-1650 cm-1 where the hybrid v7 + v8 band is located. The Ground State Combination Differences method is used for the spectra assignment. As a result more than 600 transitions of a- and b-types were founded belonging to the v7 + v8 band. Energy structure of the (v7 = v8 = 1, Bu) state is determined on the basis of assigned transitions. Further, for the inverse spectroscopic problem solution the Effective Hamiltonian model taking into account Coriolis-type interactions between states (v7 = v8 = 1, Bu) and (ν8 = ν10 = 1, Au) is used. The obtained set of spectroscopic parameters allows us to reproduce experimental data with the mean accuracy, comparable with the experimental uncertainty in line position. |
