19F/29Si rotational-echo double-resonance (REDOR) and theta-REDOR NMR techniques have been applied under fast magic-angle spinning to a powder sample of fluoride-containing octadecasil. Efficient dipolar recoupling was observed and the effect of finite pulse lengths was found to be negligible using

## 19 29 Ε½ . Fr Si Hartmann-Hahn continuous wave cross-polarization CP has been applied under fast magic-angle spinning Ε½ . MAS to a powder sample of octadecasil. Strong oscillations occur during CP on a sideband matching condition between the isolated 29 Si-19 F spin pairs formed by the silicons i
The cross-polarization dynamics between 1 H and 19 F in a Viton-type fluoroelastomer were studied using 19 F magic angle spinning (MAS) and 1 H ! 19 F cross-polarization (CP)/MAS NMR at 188.29 MHz. The phenomenological theory of spin thermodynamics based on the spin temperature hypothesis was employ
P NMR spectra of several inorganic phosphates have been examined both in the crystalline and the glassy states. The parameter (Z,&)q clearly demarcates ortho-, pyro-and meta-phosphates in terms of the "P chemical shifts. Based on such a diagram, inorganic phosphate glasses are found to consist essen
