英文摘要The technique of multiple-quantum J-resolved NMR spectroscopy (MQ-JRES) is introduced and applied to the spin system SI3-M (such as in the example given here, the (CH3)-C-13-(CH)-C-12 in alanine), The SI3 spin system was excited to its highest quantum state (8S(y)I(x)I(y)I(y)), which consists of four coherences: quadruple quantum of (3I + S), double quantum of (3I - S), double quantum of (I + S), and zero quantum of (I - S), In the MQ spectrum generated from the projection onto the F-1 dimension, the resonances of the different multiple-quantum coherences are resolved by their coupling constants to the remote spin (M), The absorptive lineshapes in both F-1 and F-2 dimensions enable accurate measurements of transverse relaxation rates, and both amplitude and relative signs of the long-range coupling constants are to be derived from either frequency or time domain data. The selective detection of MQ-JRES spectra of the individual MQ coherences using either phase cycling or pulsed field gradients is presented, 2000 Academic Press.
