Abstract
The electron-nuclear double-resonance method is used to obtain greatly enhanced NMR signals from the distant nuclei in molecular crystals which have been x irradiated to produce paramagnetic centers. Reduction of the ESR by over 98% is observed for protons in malonic acid, and the deuteron and carbon-13 NMR have also been studied in the perdeuterated crystals. Deuteron transitions have been readily detected, as well as the signals in crystals with only 1% D/H isotopic ratio.
