Title: DIRECT MEASUREMENT OF THE FUNDAMENTAL ROTATIONAL TRANSITIONS OF THE OH RADICAL AND AMMONIA BY LASER SIDEBAND SPECTROSCOPY
Creators: Blake, Geoffrey A.; Farhoomand, J.; Pickett, H. M.

Abstract: We report for the first time the direct (zero-field) spectra of rotational transitions of the OH radical in its $\Omega = 3/2$ and 1/2 states at 3036, 2509.9 and 1834.7 GHz using a recently developed far-infrared laser sideband spectrometer. These measurements have verified and refined the predictions of previous LMR work, thereby confirming the far-infrared detection of interstellar OH. We have also measured several lines of ammonia in the region from 1 to 3 THz. Comparison will be made between the experimental frequencies and predictions based on high resolution infrared spectra. The increased accuracy of these direct measurements will be useful to future astronomical and atmospheric studies of these important transitions.
