Abstract
Abstract A versatile spectrometer with facilities for modulation by the microwave-microwave double resonance effect has been constructed for the continued evaluation of the double resonance modulation (DRM) technique. Investigation of the DR signal pattern and intensity for different modes of operation indicates that optimum results are achieved with a large frequency modulation of the pump radiation, and with one pump frequency precisely on resonance. The high sensitivity of the DRM spectrometer to the effects of not exactly resonant pump radiation leads to the occurrence of multiple double resonances (DRs) and makes double resonance double search experiments practicality feasible. The double resonance map is introduced as a convenient means for the presentation of DR-spectra, and miscellaneous practical aspects are reported.
