Abstract

For several years Microwave Rotational Spectrometry (M.R.S.) has^(1,2) shown promise of becoming a powerful analytic method for polar gases. The particular features of interest in M.R.S. are the very high specificity and linearity of response over a wide dynamic range. Because of the high specificity, it is possible to measure the concentrations of several gases by the same technique, in the same instrument, with a single sample. For example one can detect and quantify any one of many sulfur containing molecules (such as OCS, SO₂, H₂S, CH₃SH, etc.) without regard to interferences. The wide range linear response provides an ease of calibration not found with most other techniques.
