Special Stark modulator for use with PTFE coated electrodes (microwave spectroscopy)
TLDR
In this paper, a Stark modulator was used to avoid voltage fluctuations due to accumulation of electric charges in microwave spectroscopy of free radicals, where high voltage was alternately applied to each electrode so that the direction of the modulation electric field changes at every period.Abstract:
When using PTFE coated electrodes in microwave spectroscopy of free radicals, voltage fluctuations due to accumulation of electric charges appear. A special Stark modulator has been used to avoid these spurious features. With this device the high voltage is alternately applied to each electrode so that the direction of the modulation electric field changes at every period.read more

Microwave Spectrum of the SO Radical
F. X. Powell,David R. Lide +1 more
TL;DR: In this article, the microwave transitions of the SO free radical in the gas phase have been measured and assigned, and the lines result from electric dipole transitions between rotational levels in the 3Σ-ground state which are strongly perturbed by the interaction of the electron spin.

Application of microwave spectroscopic techniques to the detection of transient species and to the study of reaction mechanisms
TL;DR: In this paper, a review of microwave absorption and gas-phase EPR spectroscopy applications in the detection of free radicals and short-lived molecules is presented, with reference to a number of examples: microwave absorption spectra applied to the thermal decomposition of ethylene episulphoxide, gas phase spectra to the reactions of SO and O with NO2, as well as the reaction of O + OCS → SO + CO.
