Abstract : Ramsey patterns were observed for the 168.7 Gc lines of hydrogen sulfide for the first time. A pair of interferometers separated by 10 inches was used for the Ramsey excitation. Linewidths on the order of 930 cps, equivalent to 43 at X-band, were attained. The effects of several sources of line broadening were observed and are discussed. (Author)
