Microwave spectrum and ring structure of cyclopropyl cyanide

Abstract

The microwave spectrum of cyclopropyl cyanide has been re-examined and a centrifugal distortion analysis has been carried out. Also, the two isotopic species containing 13C in the ring have been assigned allowing a substitution determination of the ring structure. Parameters found are r12 = 1.528±0.005 Å, r23 = 1.500±0.002 Å, &C2C1C3 = 58.8±0.3°.
