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.

0200746Jackson 这个为期三年的美英物理实验化学合作研究奖涉及迈克尔·杰克逊和威斯康星大学拉克罗斯分校的学生以及牛津大学物理和理论化学实验室的约翰·M·布朗。 目标是利用激光磁共振（LMR）在远红外区域进行高分辨率光谱分析。 LMR 是一种检测气相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种类，包括在高层大气中发现的一氧化氯和超氧阴离子自由基，这是最重要的生物自由基之一，也是衰老过程中的主要因素。免疫疾病和组织排斥。 他们将以高灵敏度从可见光到微波区域检查这些物种。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。 英国在不稳定小分子（自由基）的几何和电子结构方面的专业知识对此进行了补充。 该研究将增进对大气化学、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。 来自以本科为主的教学机构的学生将获得国际经验，并从 LMR 光谱仪系统培训和使用 LMR 实验技术进行自由基研究中受益。
