A single-input double-tuned probe was designed for double resonance nuclear magnetic resonance (NMR) experiments, in which high radio frequency power irradiations were achieved at two closely spaced frequencies (such as 26.1 MHz for {sup 27}Al and 28.4 MHz for {sup 65}Cu). The efficiency of the probe for both nuclei was determined to be about 80{percent}, compared to that obtained with a single-tuned probe. The probe was used successfully for {sup 27}Al{endash}{sup 65}Cu SEDOR experiments to derive the internuclear distance between Al and Cu in Cu-ZSM-5 zeolite. The circuit is ideal for SEDOR-type double resonance NMR experiments, when high power irradiation is required for nuclei with closely spaced resonance frequencies. {copyright} {ital 1998 American Institute of Physics.}
