Abstract

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.
