摘要：

The H-2 quadrupolar Carr-Purcell-Meiboom-Gill (QCPMG) NMR experiment is proposed as a convenient method to obtain detailed information about molecular dynamics in solids. Compared to the quadrupolar-echo (QE) experiment QCPMG offers two advantages. First, a sensitivity enhancement by about an order of magnitude is achieved by splitting the QE spectrum into spin-echo sidebands. Second, the lineshape of the individual sidebands provides detailed information about the molecular dynamics and increases the dynamic range by two orders of magnitude. The H-2 QCPMG method is demonstrated experimentally and numerically using the two-fold flip process in dimethyl sulfone, (C) 1998 Elsevier Science B.V. All rights reserved.
