## Abstract **Summary:** ^2^H NMR solidβstate spectra of aromatic molecules (benzene, toluene, chlorobenzene, naphthalene) included in clathrate phases of syndiotactic polystyrene (sβPS) or absorbed in the amorphous phase of sβPS, have been recorded and analyzed for a broad range of temperature (23
Proton NMR relaxation study of calcium aluminate hydrates was performed. The proton spin-lattice relaxation time (Tl,ef) was measured as a function of curing time at room temperature and at 65Β°C, respectively. At both temperatures a continuous decrease of Tl,efwith time was observed in the initial c
