Direct measurement of the fundamental rotational transitions of the OH radical and ammonia by laser sideband spectroscopy

Creators

  • 1. California Institute of Technology, Pasadena

Description

The direct (zero-field) spectra are reported for 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. Several lines of ammonia were measured in the region from 1 to 3 THz. Comparison will be made between the experimental frequencies and predictions based on high resolution infrared spectra
