Abstract

The J=1→0 transition frequencies were measured for NCCCD using a beam-maser spectrometer. Hyperfine structure from ¹⁴N and D was completely resolved. Analysis of the data directly gives the ¹⁴N and deuterium quadrupole coupling constant along the internuclear axis eqQ( ¹⁴N)=-4318.0±0.1 kHz, eqQ(D)=203.5±1.5 kHz. From the data the spin-rotation constant on ¹⁴N was also measured: C( ¹⁴N)=1.1±0.2 kHz. The spin-rotation data were used to calculate paramagnetic chemical shift tensor components σ _xx^p=σ^yyp=-593±40 ppm. These experimentally determined tensor components were combined with calculated diamagnetic tensor components to give the isotropic shift σ_av= 18±27 ppm.
