项目摘要
Many reactions occur too fast to be seen by the naked eye. Chemical reactions can occur in times that are a billion times faster than the blinking of the human eye. Understanding how these reactions happen provides essential information to be able to manipulate them to our advantage. Laser flash photolysis (LFP) is a technique employed to study these fast reactions. The reaction is started with a laser, which is a very intense light source of one color that delivers the light in a short pulse (10 ns, ten one billionth of a second). Measuring the color change due to reactant disappearance or product formation follows the chemical reactions that occur after the laser pulse. This proposal is requesting funds for the replacement for the YAG laser used in the LFP facility at the University of Victoria. This laser is 14 years old and recently failed twice with a down time of 4 weeks on the first occasion and 2 weeks on the second occasion. It is currently only working marginally. The laser is not maintained by its manufacturer because it is obsolete and for this reason it has reached the end of its lifetime. Continued access to LFP experiments is essential for the work done in the Bohne (supramolecular dynamics) and Wan (mechanistic organic photochemistry) groups, since all of their work relies on LFP experiments. Access is also critical for the Frank (photomagnetism) and Mitchell (photochromic materials) groups, since LFP experiments are essential to provide mechanistic insights into the photochromic properties of the materials studied in these groups.
许多反应发生得太快,肉眼无法看到。化学反应发生的时间可能比人类眨眼的速度快十亿倍。了解这些反应如何发生提供了必要的信息,以便能够操纵它们对我们有利。激光闪光光解(LFP)是一种用于研究这些快速反应的技术。反应是由激光开始的,它是一种非常强的单色光源,(10 ns,十亿分之一秒)在激光脉冲之后发生的化学反应之后测量由于反应物消失或产物形成而引起的颜色变化。该提案要求提供资金,以更换维多利亚大学LFP设施中使用的YAG激光器。该激光器已有14年历史,最近两次失败,第一次停机时间为4周,第二次停机时间为2周。目前,它只是在边缘工作。激光器没有由其制造商维护,因为它已经过时,并且由于这个原因,它已经达到了其寿命的终点。继续获得LFP实验对于Bohne所做的工作至关重要(超分子动力学)和万由于他们所有的工作都依赖于LFP实验,因此,弗兰克的研究也很关键。(光磁性)和Mitchell(光致变色材料)组,因为LFP实验对于提供这些组中研究的材料的光致变色性质的机理见解是必不可少的。
