ZFS-Related Paramagnetic Phenomena in NMR Spectroscopy

在这个实验物理化学项目中，密歇根大学安娜堡分校的Robert Sharp将研究顺磁性金属离子的核和电子自旋弛豫现象。将进行实验和理论工作，以更好地理解零场分裂相互作用及其对顺磁弛豫增强的影响。对电子自旋-晶格强耦合情况下的自旋运动和自旋弛豫现象进行理论描述，并对海森堡交换耦合多核金属中心的自旋弛豫特性进行实验和理论研究。这些研究将为磁共振成像造影剂的设计和金属酶的结构提供信息。磁共振成像是一种应用广泛的诊断技术。为了在低场强下获得可能的最大分辨率，有必要了解对比机制。本研究提供的信息将有助于设计对比剂，以提高图像质量和提高灵敏度。

In this project in the Experimental Physical Chemistry Program, Robert Sharp of The University of Michigan at Ann Arbor will study nuclear and electron spin relaxation phenomena of paramagnetic metal ions. Experimental and theoretical work will be conducted to obtain a better understanding of zero field splitting interactions and their effect on paramagnetic relaxation enhancements. A theoretical description of spin motion and spin relaxation phenomena in cases of very strong electron spin-lattice coupling will be developed, and experimental and theoretical studies of the spin relaxation properties of Heisenberg exchange-coupled polynuclear metal centers will be undertaken. These studies will provide information relating to the design of contrasting agents for Magnetic Resonance Imaging and structures of metallo-enzymes. Magnetic Resonance Imaging is a widely used diagnostic technique. In order to obtain the maximum resolution possible at low field strengths, an understanding of the contrast mechanisms is necessary. This research will provide information which will assist in the design of contrasting agents to enhance image quality and improve sensitivity.
