✦ Synopsis

Hydrated aluminophosphate AIPO,-8 has been studied by fast "AI magic-angle-spinning (MAS) NMR at 4.7 and 9.4 T, 'H-*'AI MAS NMR with cross-polarization (CP/MAS) and by quadrupole nutation NMR. The material contains four and possibly five crystallographically inequivalent sites for aluminium
