The 2+2→3−2 rotational transition in water vapor has been carefully studied by using both a simple video and a double modulation millimeter wave spectrometer. The line center remeasured is ν0 = 183 310.12±0.10 Mc/sec. Self-broadening and foreign-gas broadening were investigated over the pressure range of 5 to 400 μ of Hg with the following results: Perturbing gasΔν/p (Mc/sec·mm)H2O19.06CO26.09N23.76O22.72Ar1.97. These results, obtained by the double modulation spectrometer, have been compared with other line broadening studies, and for the first time linewidth calculations on asymmetric molecules appear to be valid.
