摘要：

The ground-state microwave spectra of acetonitrile and acetonitrile-d3 and their 13C and 15N isotopic species have been remeasured between 8 and 240 GHz. The derived quartic centrifugal distorition constants are in very good agreement with the values calculated from the general harmonic force field. The rotational constants we have obtained allow us to calculate very accurate rs and rz structures. The rz structure is: r(CC), 1.4617 (6) Å; r(CN), 1.1567 (6) Å; r(CH), 1.0947 (24) Å; {measured angle}(CCH), 109.85° (10). This structure shows no significant difference from the parameters derived in an earlier electron diffraction study. © 1979.
