dc.description.abstractRecently, Freeman and Morris and Morris proposed the use of the nonselective polarization-transfer (PT) pulse train (90xH)-r-( 180XH)(1 80xI)-t-(90j,H) X (90xI)-A-(acquire data, decouple) as a general technique for enhancing the NMR signals from a nucleus I with a low gyromagnetic ratio. The sequence is particularly useful when the relaxation mechanism of nucleus I arises from nonproton dipolar interactions, a consequence of which is negligible nuclear Overhauser enhancement (NOE) after proton decoupling. Fundamental to NMR is the general rule that, provided the relaxation pathway of a nucleus I is dominated by *H-I dipolar couplings, the NOE is independent of the number of relaxing protons, being 1 + 7h/27i provided the extreme narrowing limit applies.en_US
