Relaxation-induced polarization transfer and the determination of methyl group C-13 chemical shielding anisotropy
Numerous pathways by which nuclear spin polarization is transferred, rather than dissipated, through the spin relaxation process can be identified and exploited. In this study, application of relaxation-induced polarization transfer has been implemented to obtain the C-13 chemical shielding anisotropy (-23 +/- 6 ppm) of the methyl group in methylcobalamin dissolved in D2O (300 K).
