U.S.-U.K. Cooperative Research: High Resolution Spectroscopy of Free Radicals Using Laser Magnetic Resonance

0200746杰克逊这个为期三年的奖项是为美英在物理实验化学方面的合作研究而设立的，参与者包括迈克尔杰克逊和威斯康星州大学的学生拉克罗斯和约翰M。布朗在牛津大学的物理和理论化学实验室。 目的是使用激光磁共振（LMR）在远红外区域进行高分辨率光谱分析。 LMR是一种用于检测气相中瞬态物质并研究其旋转或振动-旋转光谱的技术。 研究人员建议研究几种重要的分子物种，包括在高层大气中发现的一氧化氯，以及超氧阴离子自由基，这是最重要的生物自由基之一，也是衰老过程，自身免疫疾病和组织排斥的主要因素。 他们将从可见光到微波区域对这些物种进行高灵敏度的研究。美国研究人员为该项目带来了远红外区域LMR研究的专业知识。 英国在小的不稳定分子（自由基）的几何和电子结构方面的专门知识对此进行了补充。 这项研究将促进对大气化学、天文学、生物学和生物医学研究领域感兴趣的自由基的结构和行为的理解。 来自主要本科教学机构的学生将获得国际经验，并受益于LMR光谱仪系统的培训和使用LMR实验技术的自由基研究。

0200746JacksonThis three-year award for US-UK cooperative research in physical experimental chemistry involves Michael Jackson and students at Unviersity of Wisconsin La Crosse and John M. Brown at Oxford University's Physical and Theoretical Chemistry Laboratory. The objective is to perform high-resolution spectroscopy in the far-infrared region using laser magnetic resonance (LMR). LMR is a technique for the detection of transient species in the gas phase and the study of their rotational or vibrational-rotational spectra. The researchers propose to investigate several important molecular species, including chlorine monoxide, which is found in the upper atmosphere, and the super oxide anion radical, which is one of the most important biological free radicals and a major factor in the aging process, auto-immune diseases and tissue rejection. They will examine these species at high sensitivity from the visible to microwave regions.The US investigator brings to this project expertise in LMR studies in the far-infrared region. This is complemented by British expertise in geometrical and electronic structures of small unstable molecules (free radicals). The study will advance understanding of the structure and behavior of free radicals of interest to the fields of atmospheric chemistry, astronomy, biology and biomedical research. Students from a predominantly undergraduate teaching institution will gain international experience and benefit from training in LMR spectrometer system and studies of free radicals using LMR experimental techniques.
