We. Jones et al., Far-infrared LMR spectroscopic investigation of the quasi-linear molecule DCCN: The nu(5)(1 <- 0), CAN J PHYS, 79(2-3), 2001, pp. 389-408
The far-infrared laser magnetic resonance spectrum (FIR LMR) of the v(5) be
nding vibrational transition of DCCN in its X-3 Sigma (-) State is reported
. The DCCN radical was produced inside the spectrometer cavity by the react
ion of deuterated acetonitrile with F atoms. DCCN resonances were measured
on seven laser lines. Nitrogen hyperfine structure was observed on a number
of the resonances. The analysis provides improved accuracy for the separat
ion v(5) = 1 <-- 0 and some of the N-14 hyperfine coupling constants for th
is isotopomer.
