Abstract
The IR spectrum of the CH2D2 molecule has been measured in the region of 2350-2650 cm-1 on a Bomem DA002 Fourier transform spectrometer with a resolution of 0.004 cm-1 (FWHM, apodized) and analyzed with a Hamiltonian model which takes into account resonance interactions between all vibrational states in that region. More than 3000 transitions have been assigned to the bands and 2ν9, ν3 + ν4, ν5, + ν9, ν5 + ν7, and ν3 + ν7 using ground state combination differences from the known ground state parameters. A set of 115 spectroscopic parameters for the excited vibrational states is obtained from a least squares adjustment. This reproduces the 646 initial upper ro-vibrational energies used in the fit with a drms = 0.0036 cm-1.
