Abstract

We report the detection of 13 rotational transitions in the first excited bending state (010) of CD₂ using the technique of far-infrared laser magnetic resonance spectroscopy. Molecular parameters for this state are determined from these new data together with existing infrared observations of the ν₂ band. Additional information on the ground vibrational state (000) is also provided by the observation of a new rotational transition, and this is combined with existing data to provide a refined set of molecular parameters for the CD₂ ground state. One spectrum has been observed that we assign as a rotational transition within the first excited symmetric stretching state (100) of CD₂. These data will be of use in refining the structure and the potential function of the methylene radical.
