U.S.-Korea-Australia Cooperative Science: Solid State NMR, X-ray and Neutron Diffraction Study of Inorganic Nitrates

INT-0096919 Shore本研究的目标是更好地了解导致无机硝酸盐形成的能量学和动力学。一系列的无机硝酸盐将使用变温固态核磁共振光谱和变温衍射测量进行研究。原子的位置和静电相互作用的特点。然后，这些测量将与来自NMR光谱的硝酸根离子的运动的测量相关联，并且将用于开发与温度依赖行为一致的原子级模型。通过这个模型，我们可以更好地理解无机硝酸盐的动力学和静电相互作用之间的关系。这项工作也将导致更好地了解含有多原子离子的离子材料的形成。该项目启动了来自美国，韩国和澳大利亚的研究人员之间的合作，这些研究人员具有互补的专业知识和研究能力。美国小组将提供固态核磁共振测量，韩国小组将提供中子衍射测量，澳大利亚小组将提供单晶X射线衍射测量。这种合作有可能是长期的，并提供许多重要的固态无机材料的基本理解。

INT-0096919 ShoreThe goal of this research is to better understand the energetics and dynamics that lead to the formation of inorganic nitrates. A series of inorganic nitrates will be studied using variable temperature solid-state NMR spectroscopy and variable temperature diffraction measurements. The atomic positions and electrostatic interactions will be characterized. These measurements will then be correlated with the measurement of the motion of the nitrate ion, from NMR spectroscopy, and will be used to develop an atomic-level model that is consistent with the temperature dependent behavior. With this model, a greater understanding of the relationship between dynamics and electrostatic interactions in inorganic nitrates will be obtained. This work will also lead to a better understanding of the formation of ionic materials that contain polyatomic ions.This project initiates a collaboration between investigators from the United States, South Korea, and Australia that have complementary expertise and research capabilities. The United States group will provide the solid state NMR measurements, the South Korean group will provide the neutron diffraction measurements, and the Australian group will provide the single crystal X-ray diffraction measurements. This collaboration has the potential to be long term and to provide fundamental understanding of many important solid state inorganic materials.
