Abstract
A high resolution spectrum of the formaldehyde D2 12CO molecule in the range from 1780 to 2400 cm-1 has been recorded by a Fourier transform infrared spectrometer. The measured region covers the stretching fundamental bands ν1 and ν5 and the first overtone and combination bands 2ν4, ν4+ν 6, 2ν6, ν3+ν4, ν3+ν6, and 2ν3 which correspond to double excitations of deformational quanta. About 9600 transitions were assigned to the eight mentioned vibrational bands. Preliminary analysis with J′<10 of the obtained assignments was made, and the values of the band centers and the main rotational, centrifugal distortion, and resonance interaction parameters were estimated.
