This effect is either positive or negative depending on the difference between the quantum transition probabilities omega-sub-two and omega-sub-zero.
A device that exploits this effect is the only quantum magnetometer that offers continuous or sequential operation; that magnetometer was introduced by GEM Systems. This effect is either positive or negative depending on the difference between the quantum transition probabilities omega-sub-two and omega-sub-zero. The first experimental test of it was performed by Carver and Slichter with metallic lithium. This effect can be eliminated by the addition of chromium(III) acetylacetonate. Experiments using it usually turn off the decoupler when acquiring the free induction decay, as opposed to HOMODEC experiments. It causes the spin populations of non-irradiated nuclei to change provided that an irradiated nuclei is causing T1 relaxation of them by the dipole-dipole mechanism. For 10 points, identify this type of dynamic nuclear polarization observed in NMR spectroscopy.
