This band gains appreciable intensity as a result of high anharmonicity of the potential. A total of over 100 lines have been observed. The observed frequencies agree well (within $0.05 cm^{-1})$ with first principles $calculations^{1}$ based on the ab initio potential of Meyer. Botschwina, and $Burton^{2}$ with adjusted parameters. This observation provides information on the assignment of the laboratory FTIR emission spectrum of a vibrationally and rotationally hot deutenum $plasma^{3}$ produced in a hollow cathode by Majewski, McKellar, and Watson. en_US dc.format.extent 61171 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title OBSERVATION OF THE $2\nu_{2} (l = 2)$ OVERTONE BAND OF D en_US dc.type article en_US
