Abstract

The infrared spectrum of the formaldehyde D213CO molecule in the 650-1200 cm^-1 region has been analyzed based on high-resolution FTIR spectra. The quantum number limits of 10 150 assigned transitions are J_max = 48, and K_{a, max} = 17. The observed energy levels of the (v ₃ = 1), (v₄ = 1), and (v₆ = 1) states have been introduced to a fit in order to obtain parameters of the Watson's A-type Hamiltonian and A-, B-, and C-type Coriolis coupling constants. The obtained band centers of ν₃, ν₄, and ν₆ bands are 1099.671488(18), 923.3556824(18), and 980.1687408(16) cm^-1, respectively. The standard deviation of the fit is 0.00019 cm^-1.
