 Title: FAR INFRARED LMR SPECTROSCOPIC MEASUREMENTS OF THE QUASI-LINEAR MOLECULE DCCN Creators: Jones, W. E.; Sun, F.; Curl, R. F., Jr.; Allen, M. D.; Evenson, K. M.; Brown, J. M. Issue Date: 2000 Publisher: Ohio State University Abstract: FIR laser magnetic resonance spectra of the quasilinear free radical DCCN, produced by fluorine atom abstraction of deuterium from deuterated acetonitrile $(CD_{3}CN)$, has been measured at laser wavelengths between 46 and $136 \mu m$. The spectra have been analyzed using a triplet asymmetric rotor Hamiltonian. Included in the fitting data set are the millimeter wave $data ^{a}$ for the $\nu_{5}=0$ and 1 levels. This analysis has allowed the determination of some Zeeman constants and the refinement of the molecular constants of DCCN. Description: $^{a}$M. C. McCarthy, C.A. Gottlieb, A.L. Cooksy, and P.
