## Abstract A simple analytical method based on the memoryβfunction approach and the AndersonβWeiss theory is presented for studying in a uniform way the spin dynamics in several NMR experiments performed under the conditions of magicβangle spinning (MAS). A series of ^1^H MAS spectra of adamantane
The broadenings observed in "C MAS NMR spectra, which depend on the sample-spinning speed, were studied, using polycrystalline adamantane. Not only was a monotonic increase of the linewidths with the increase of the spinning frequency observed, but also a novel resonant feature was found. The phenom
A simple NMR experiment for the dephasing of the rotational echo amplitudes of homonuclear dipolar coupled spin pairs in solids rotating at the magic angles is described. The dephasing is generated by n pulses applied synchronously with the sample rotation. One n pulse per rotor cycle is sufficient
