This award supports Dr. Erhard W. Rothe of Wayne State University for several trips to Goettingen, Germany, to collaborate in chemical physics research with Dr. Peter Anderson of the Max Planck Institute for Flow Research. They are studying interactions of pulsed ultraviolet laser light with molecules. One set of experiments they will carry out involves laser preparation of single quantum states and study of their subsequent interactions with molecules and/or with other laser light. This requires the use of three lasers on the same experiment. The second type of research is more applied and involves a new method, developed at the Max Planck Institute, for laser analysis of combustion involving laser.induced predissociative fluorescence (LIPF). Much remains to be done to make a quantitative analysis system for a large number of species. This will be the subject of joint effort. This collaboration offers the possibility of enhancing automotive combustion diagnostics in the Detroit area through direct experience with highly competent and well equipped German collaborators. Lasers offer many desirable features for application to chemical diagnostics. They have high intensity, narrow band.width, fast pulses and coherence. The light is easily manipulated and focussed with mirrors and lenses. Appropriate combinations of such desirable properties can be readily exploited. LIPF offer the particular advantage that it can be quantitatively and simply used at atmospheric and higher pressures, such as those that exist, for example, with atmospheric flames or with internal combustion. Such techniques are particularly promising when combined detector and computer technologies are applied to combustion. These should, for example, lead to optimization of fuels and minimization of pollutants by appropriate control and feedback technology. Such quick, accurate and simple techniques are applicable to a variety of commercial processes, including low and high temperature turbulent environments.

该奖项支持韦恩州立大学的埃尔哈德·W·罗斯（Erhard W. 他们正在研究脉冲紫外线激光与分子的相互作用。 它们将进行的一组实验涉及激光制备单个量子状态，并研究其随后与分子和/或其他激光的相互作用。 这需要在同一实验上使用三个激光器。 第二种研究的应用更具应用，并涉及在Max Planck Institute开发的一种新方法，用于激光分析涉及激光的燃烧。 为大量物种建立定量分析系统还有很多要做的事情。 这将是共同努力的主题。 这项合作提供了通过与高能力且设备齐全的德国合作者的直接体验来增强底特律地区汽车燃烧诊断的可能性。 激光器为化学诊断提供了许多理想的功能。 它们具有高强度，狭窄的带。宽度，快速脉冲和连贯性。 光很容易被操纵，并用镜子和镜头聚焦。 可以很容易利用这种理想特性的适当组合。 LIPF提供了一个特殊的优势，即可以在大气和更高的压力上进行定量和简单地使用，例如存在大气火焰或内燃烧的压力。 当将探测器和计算机技术应用于燃烧时，这种技术尤其有希望。 例如，这些应该通过适当的控制和反馈技术来优化燃料和最小化污染物。 如此快速，准确和简单的技术适用于各种商业过程，包括低温和高温湍流环境。
