MICROWAVE SPECTROSCOPY OF OXYGEN MOLECULE
Abstract
A %) KC STARK MODULATED MICROWAVE SPECTROMETER FOR THE ()) MC FREQUENCY REGION WAS CONSTRUC ED. The absorption cell is a cavity resonator which tunes smoothly with continuous frequency coverage. Con ections to the septum allow the superposition of radio frequency electric or magnetic fields at frequencies of the ord r of 10 mc. This fe ture is used for double resonance, or three-level maser-type, spec ro copy. The semicl ssical radi tion theory for a three-level qua tum system indicates that very weak radio fr quency transitions should be observable by the interference of the weak transition with the stronger microwave transition. Experime tal difficul ies have prevented confirmation of the theory. Direct pickup or electrical interference effects between the rf generator when it is turned on and off (as is necessary to furnish modulation information) and the microwave detection unit have masked the w ak physical effect to be observed.
