High resolution infrared study of D2CO in the region of 1780-2400 cm-1: Assignment and preliminary analysis

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.
