Structures, Dynamics, and Electronic States in Quasicrystalsand Small Clusters: Nuclear Magnetic Resonance Studies

这是对结构的核磁共振（NMR）研究， 动力学和量子限制小团簇中的电子态 和二十面体合金。 该研究将涉及开发 先进的核磁共振技术， 原子环境的特点，内部原子在集群， 以及表面原子。 通过分别监控内部和 表面，这将是可能的，以了解散装和表面 熔化过程，并研究附近的晶格动力学 熔点 双共振技术及其改进 它将被用来研究主客体之间的相互作用， 包合物簇和分子筛骨架，例如 磷酸铝筛材料。

This is an nuclear magnetic resonance (NMR) study of the structure, dynamics, and electronic states in quantum-confined small clusters and icosohedral alloys. The research will involve development of sophisticated NMR techniques that will allow the resolution of atomic environments characteristic of interior atoms in clusters as well as surface atoms. By separately monitoring the interior and the surface, it will be possible to understand the bulk and surface melting process and to investigate the lattice dynamics near the melting point. Th double resonance technique and refinements thereof wil be used to study host-guest interactions between inclusion clusters and molecular sieve frameworks, such as aluminophosphate sieve materials.
