H-2 quadrupolar Carr-Purcell-Meiboom-Gill NMR for paramagnetic solids
H-2 (I = 1) quadrupolar Carr-Purcell-Meiboom-Gill (QCPMG) NMR methods in the presence of a paramagnetic shift interaction are reported. Pulse sequences based on quadrupole echo that can compensate effect of the shift interaction were adapted to obtain undistorted QCPMG spectra. The methods were demonstrated by H-2 NMR measurement for paramagnetic CoSiF6.6H(2)O using strong radio-frequency pulses and by computer simulation. Detection of molecular dynamics by the present QCPMG method was also examined. (C) 2011 Elsevier B. V. All rights reserved.
