英文摘要A transient nuclear Overhauser effect (NOE) makes measurements of the C-13 spin-lattice relaxation times in organic solids complicated. Extended Solomon equations are applied in order to describe C-13 spin-lattice relaxation with H-1 r.f. field irradiation. Spin-lattice relaxation under r.f. irradiation is shown to be generally a triple-exponential process, but it can be reduced to be single-exponential under stronger r.f. field irradiation as well as in the absence of H-1 initial magnetizations. Based on numerical calculations, the difference between spin-lattice relaxation curves obeying T-1(C)T-1(H) is clearly indicated. The methyl group resonances in solid-state L-valine are examined, and the experimental results agree well with the theoretical results. (C) 1997 Elsevier Science B.V.
