The spectrum of CH2D2 has been recorded with a Fourier transform Bruker IFS HR spectrometer with a resolution of 0.003 cm-1. From 4200 lines recorded in the 900-1550 cm-1 region, 861 have been assigned to ν4(A1), 954 to ν7(B1), 859 to ν9(B2), and 763 to ν3(A1) absorption bands, respectively. Simultaneous fitting of all experimental data has been made. Rotational, centrifugal, and resonance parameters obtained reproduce the initial experimental data within an average accuracy of 15 × 10-5 cm-1.
