Abstract
Two infrared absorption bands of CH2D2 have been analyzed in the semirigid rotor approximation. These are the A-type band at 2671.67 cm−1 and the C-type band at 4425.61 cm−1. The A-type band has previously been assigned as v3+v9, and the C-type band is tentatively assigned as v3+v6 The upper state of the A-type band is perturbed presumably by the close lying level 2v5. This interaction has not been investigated. The following values were found for the rotational constants of the ground vibrational state: A0=4.303 cm−1, B0= 3.504 cm−1, C0= 3.049 cm−1.
