Abstract
The response of triads of strongly coupled spin-1/2 nuclei to the generalized Goldman-Shen pulse sequence ( alpha )phi - tau 1-( alpha )phi +180 degrees - tau 2-( beta )0 degrees is reconsidered by taking into account the spin diffusion between the equidistant energy-level pairs of the spin-rotor system during the time tau 2. The refined theory gives quantitatively correct model responses and sheds new light on the discrepancy between the previous theory for an ensemble of isolated triads and the analogous theory for pairs of coupled triads, in the limit of no coupling. Theoretical three-pulse spectra are compared with experimental responses of the tunnelling methyl protons in a CH3COONa.3D2O single crystal at 30 K.
