Spectra and structure of small ring compounds
TL;DR: In this paper, it was shown that the O-H moiety has both the gauche and trans conformations present in the equatorial form but only the conformer is present in axial form of the ring.

James R. Durig,Y. S. Li +1 more
TL;DR: In this article, the microwave spectrum of isopropyl cyanide, (CH 3 ) 2 CHCN, has been recorded from 26.5 to 40.0 GHz and the R-branch assignments have been made for the ground and three different excited states.

A Stark-effect microwave spectrograph of high sensitivity.
TL;DR: A microwave spectrograph is described in which the absorption of the gas being studied is modulated by the application of a periodic Stark‐effect field so that the output of the crystal detector contains a radiofrequency component which can be amplified with a narrow‐band amplifier.
