“…This bonding model appears to be a good approximation even for phenyl cyanide, since g = À0.080 [39] is also fairly close to zero. The principal quadrupole tensors of acetyl cyanide, cyanoketene, and cyanocyclopropenylidene display larger deviations from cylindrical symmetry with g values of about 0.19 [44], À0.37 [41], and 0.38 [42], respectively. As mentioned above, the value of cyanoketene is somewhat more uncertain.…”

a b s t r a c tRotational transitions of iso-propyl cyanide, (CH 3 ) 2 CHCN, also known as iso-butyronitrile, were recorded using long-path absorption spectroscopy in selected regions between 37 and 600 GHz. Further measurements were carried out between 6 and 20 GHz employing Fourier transform microwave (FTMW) spectroscopy on a pulsed molecular supersonic jet. The observed transitions reach J and K a quantum numbers of 103 and 59, respectively, and yield accurate rotational constants as well as distortion parameters up to eighth order. The 14 N nuclear hyperfine splitting was resolved in particular by FTMW spectroscopy yielding spin-rotation parameters as well as very accurate quadrupole coupling terms. In addition, Stark effect measurements were carried out in the microwave region to obtain a largely revised c-dipole moment component and to improve the a-component. The hyperfine coupling and dipole moment values are compared with values for related molecules both from experiment and from quantum chemical calculations.

“…[12] were made in supersonic expansion, at 7-19 GHz, with the cavity Fourier transform microwave spectrometer (FTMW) in Warsaw [14]. This spectrometer is a coaxial waveguide version of the original design of Balle and Flygare [15], which has recently been upgraded to a simple computer aided single-step frequency downconversion [16].…”
