摘要：

The use of the dipolar-narrowed Carr-Purcell sequence for measuring the spin-lattice contribution to the linewidth under multiple pulse sequences is demonstrated. The relaxation in polyisoprene is exponential with a time constant, T1y, of the order of T1p for the sample. The relaxation rate depends on pulse spacing in a manner not predicted by assuming an exponential correlation function for the reorientation. © 1979 American Institute of Physics.
