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

迈克尔·杰克逊和威斯康星大学拉克罗斯大学的学生以及牛津大学物理化学和理论化学实验室的约翰·M·布朗获得了这一为期三年的物理实验化学合作研究奖。其目标是使用激光磁共振(LMR)在远红外区域执行高分辨率光谱。激光磁共振是一种检测气相中的瞬变物质并研究其转动或振动-转动光谱的技术。研究人员建议研究几个重要的分子物种，包括高层大气中发现的氯一氧化碳，以及超氧阴离子自由基，后者是最重要的生物自由基之一，也是衰老过程、自身免疫性疾病和组织排斥反应的主要因素。他们将在从可见光到微波的高灵敏度范围内检查这些物种。美国研究人员为这个项目带来了远红外区LMR研究方面的专业知识。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补充了这一点。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了解。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光谱仪系统的培训和使用LMR实验技术研究自由基中受益。

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.
