The high resolution IR spectrum of the CH2double bond; length as m-dashCD2 ethylene isotopomer was recorded and analyzed in the region of 1300–1450 cm?1, where the strongly interacting bands ?12(A1) and 2?10(A1) are located (the band ?12 was analyzed earlier; transitions belonging to the 2?10 band 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 not only resonance interactions between the states (v12=1) and (v10=2), but interactions of the mentioned pair of vibrational states with the states (v7=v10=1) and (v7=2), as well. More than 1960 and 320 transitions with the values View the MathML source and View the MathML source were assigned to the bands ?12(A1) and 2?10(A1), respectively. A set of 59 spectroscopic parameters was obtained from a weighted least square fit procedure. This reproduces the 959 and 180 initial upper ro-vibrational energies of the vibrational states ?12(A1) and 2?10(A1) used in the fit with a View the MathML source and View the MathML source, respectively (in this case, only upper energies obtained from unblended and nonsaturated transitions of relatively high intensities have been taken into account). The ground state rotational parameters were improved in comparison with the parameters known in the literature.
