Symmetry-Based Si Dipolar Recoupling Magic Angle Spinning NMR Spectroscopy: A New Method for Investigating Three-Dimensional Structures of Zeolite Frameworks.
The article presents a study related to important properties and applications of zeolites which are intimately related to their three-dimensional (3D) framework structures. However, structure determination of these materials by diffraction techniques is difficult since single crystals of adequate di...

However, structure determination of these materials by diffraction techniques is difficult since single crystals of adequate dimensions are usually not available. Solid-state NMR can provide structural information that is complementary to diffraction, particularly with the development of dipolar recoupling magic angle spinning NMR pulse sequences by which internuclear distances can be probed. In this communication, it is demonstrated that through-space dipolar interactions between naturally abundant Si nuclei in pure silica zeolites can be exploited to provide information about the 3D structures of zeolite frameworks, including bonding connectivities as well as long-range distance information between Si sites. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2005 holdings: @attributes: islocal: N |
