✦ Synopsis

A simple two-dimensional NMR procedure is used to obtain high-resolution chemical shift-dipolar correlated spectra of magicangle spinning solids. The dipolar spectrum in the second dimension is obtained without rotational sidebands as the result of Fourier transform of reverse cross-polarization evolution. For a finite number of localized interactions between dilute spins and their abundant neighbours, strong transient oscillations can be observed with high sensitivity. leading to well-resolved unscaled dipolar splittings.
