The band has been identified and measured in the laboratory spectrum of the CD molecule for the first time. The emission from the discharge was observed with a high accuracy dispersive optical spectroscopy technique using a plane-grating spectrograph and recorded by a photomultiplier tube. In total, 99 ro-vibronic frequencies were measured with an absolute accuracy of about cm. In the following work, we present the results of the combined analysis of the current experimental data and the (0−0) [Szajna et al., J. Mol. Spectrosc. 324, 48–52 (2016)] and (0−0) [Herzberg and Johns, Astrophys. J. 158, 399–417 (1969)] bands of CD. The resulting data, compared to those from the earlier measurements, present more accurate molecular constants for the v = 0 vibrational level of the and states. The parameters of the Λ-doubling (p, q) of the (v = 0) level were obtained for the first time. The current observations and analysis have become a basis to discuss the possible detection of the CD radical in the interstellar medium by the , + and spectral lines of the band in the 3880 Å region.
