High Resolution Solid-State NMR of Silicate and ZeolitesWiley, 1987 - 485 strán (strany) Covers the dramatic developments in the past decade in the applications of high-resolution NMR to the study of solid materials such as inorganic silicates, aluminosilicates, and in particular, zeolites. Also covers a variety of NMR methods, including conventional FT NMR techniques, used to investigate sorbate-sorbent interactions and the structure of adsorbed molecules. Gives an historical background to the subject and a concise survey of basic principles and methods of high-resolution solid-state NMR. Then covers 29Si NMR of silicate solutions; general aspects of 29Si and 27Al NMR of the silicate and aluminosilicate framework; application of 29Si and 27Al NMR to silicates, aluminosilicates, and zeolites; NMR studies of nuclei other than 29Si and 27Al in zeolites and non-zeolitic silicates; high-resolution studies of adsorbed molecules, and much more. |
