| Streszczenie: | Title screen The high resolution IR spectrum of the trans-d2-ethylene (trans-C2H2D2) was recorded and analyzed in the region of 1450-1750 cm−1, where the strongly interacting bands ν8+ν10, ν7+ν8, ν6+ν10, and ν6+ν7 are located (one of the sub-bands of the hybrid ν7+ν8 band was analyzed earlier; transitions belonging to the three other bands were experimentally recorded and assigned in the present study for the first time). For description of the upper ro-vibrational energy levels obtained from the assigned transitions, the used Hamiltonian takes into account resonance interactions both between four studied vibrational states, (v8=v10=1), (v7=v8=1), (v6=v10=1), (v6=v7=1), and between the state (v6=v7=1) and the additional fifth state (v4=v8=1) which is considered in the present study as a “dark” state. About 2360, 2150, 2020 and 1700 transitions with the values =31/21, 44/18, 28/18 and 27/17 were assigned to the bands ν8+ν10, ν7+ν8, ν6+ν10, and ν6+ν7, respectively. A set of 103 spectroscopic parameters was obtained from a weighted least square fit procedure. This reproduces the 550, 656, 441 and 435 upper ro-vibrational energies of the vibrational states (v8=v10=1), (v7=v8=1), (v6=v10=1) and (v6=v7=1) used in the fit with a , which is close to the value of the mean experimental uncertainty (in this case, only upper energies obtained from unblended and nonsaturated transitions of relatively high intensities have been taken into account).
