Molecular and Magnetooptical Spectroscopy

在化学系实验物理化学项目的支持下，弗吉尼亚大学化学系的保罗·N·沙茨将使用磁圆二向色性和磁圆偏振发光光谱来研究在极低温度下分离在惰性气体基质中的物种。具体地说，他计划研究各种具有生物学意义的分子，如酞菁或含卟啉的夹心型化合物，在这种化合物中，金属离子同时配位到两个或多或少平行的平面型酞菁或卟啉环上。通过将磁光光谱学与激光烧孔技术相结合，应该可以获得关于激发态g值、分子内电子和Jahn-Teller相互作用以及晶场类型相互作用的特殊程度的详细信息。

With support from the Experimental Physical Chemistry Program of the Chemistry Division, Paul N. Schatz in the Department of Chemistry at the University of Virginia will use magnetic circular dichroism and magnetic circularly polarized luminescence spectroscopies to study species isolated in noble gas matrices at very low temperatures. Specifically, he plans on studying a variety of molecules of biological significance such as phthalocyanine or porphyrin-containing sandwich type compounds in which a metal ion is simultaneously coordinated to two more-or-less planar and parallel phthalocyanine or porphyrin rings. By combining magnetooptical spectroscopy with laser hole-burning techniques, it should be possible to obtain an exceptional degree of detail about excited state g-values, intramolecular electronic and Jahn-Teller interactions and crystal field-type interactions.
