Spectra and structure of small ring compounds. Microwave spectrum of cyanocyclobutane
TL;DR: In this article, the rotational spectrum of cyanocyclobutane has been investigated in the region 18.0-40.0 GHz, and the dipole moment components were determined to be μ a = 4.04 ± 0.09 D and μ c = 0.92 − 0.03 D. The microwave data are consistent with a bent equilibrium ground state for the ring with the cyano-group in the equatorial position.

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.
