Japan STA Program: Quenching of Gaseous Fluroescence by Large Magnetic Fields and Magnetic Field Effects on Reaction Products After Excitation

9602496 SISK该奖项支持日本科学技术厅(STA)为Wade Sisk博士提供的24个月的博士后奖学金，该奖学金授予位于日本崎玉和歌市的理化学研究所(RIKEN)。Sisk博士将与Hisaharu Hayashi博士合作开展一项研究项目，题为“高达10T的大磁场对气体荧光的猝灭以及激发后对反应产物的磁场效应”。关于气相分子化学反应的研究以前是在普通领域(H2.5T)进行的。这项拟议的研究将研究气体分子与大磁场(H2.5T)的化学反应。当分子被激发时，例如通过激光应用，它可以通过发射光(荧光)而松弛到其初始状态。因此，检测荧光水平是监测化学反应的反应物或产物的有效方法。当分子在规定的磁场中被激发时，荧光的大小也会改变。在拟议的研究中，荧光猝灭和时间分辨吸收光谱将在不同的应用(重点是磁场)的影响下进行，以：1)更全面地了解大磁场如何猝灭气相候选中的荧光；2)确定大磁场对复杂反应机制的长期影响。***

9602496 Sisk This award supports a 24 month Science and Technology Agency of Japan (STA) Postdoctoral Fellowship for Dr. Wade Sisk at the The Institute of Physical and Chemical Research (RIKEN), Wako, Saitama, Japan. Dr. Sisk will work with Dr. Hisaharu Hayashi, on a research project entitled, "Quenching of Gaseous Fluorescence by Large Magnetic Fields up to 10 T and Magnetic Field Effects on Reactions Products After Excitation". Research on the chemical reaction of gas phase molecules has previously been carried out at ordinary fields (H2.5 T). The proposed study will investigate the chemical reactions of gaseous molecules with large magnetic fields (H2.5 T). When a molecule is excited, e.g. via laser light application, it may relax to its intial state through the emission of light (fluorescence). Accordingly, the examination of levels of fluoresence is an effective way to monitor reactants or products of a chemical reaction. When a molecule is excited in the presence of a defined magnetic field, the magnitude of the fluorescence is also altered. In the proposed research, fluorescence quenching and time- resolved absorbance spectro-scopy will be carried out under the influence of different applications (the emphasis on magentic fields) in order to: 1) gain a more comprehensive understanding of how large magnetic fields quench fluorescence in gasphase candidates; 2) ascertain the long- term effects that large magnetic fields have on complicated reaction mechanisms. ***
