Sizeable pure tensor polarization of deuterons in a solid

A new effect of dynamic nuclear orientation has been observed in deuterated 1, 2-ethanediol, (CD 2 OH) 2 , at 0.12 K in a magnetic field of 25 kG: a strong RF field applied at a frequency slightly different from the proton Larmor frequency changes the deuteron tensor polarization. Mechanisms for this effect are proposed.
