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 Jmax = 48, and Ka, 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.
