An improved spin-diffusion experiment for the exploration of local order in solids is described. By slow magic-angle sample spinning, it is possible to remove the dependence of the spin diffusion rate on the chemical shift difference between two interacting nuclear spins, while the informative chemi
Proton spectra of solids are usually broadened by strong proton homonuclear dipolar interactions. However, substantial line narrowing may be achieved by Magic Angle Spinning (MAS) in systems of low proton density or in systems in which rapid molecular motions occur. In such conditions, T1(H) measure
## Abstract Magicβangle spinning (MAS) has recently been shown to enhance spectral resolution in NMR examinations of intact biological tissue ex vivo. This work demonstrates that freezing certain tissue samples before examination by ^1^H MAS NMR can have a marked effect on their spectra. Spectra of
We have investigated the carbon line shape of solid adamantane 30 kHz, the fastest rate available to us, does still not lead under high-speed magic-angle sample spinning (MAS) acquired to a ''liquid-like'' spectrum with a 1:2:1 J-splitted triplet without proton decoupling. The CH-group shows a spinn
