Experiments will be developed to illustrate the use of laser techniques in demonstrating and understanding chemical principles. Emphasis will be placed on the use of a helium-neon laser source which is inexpensive, safe, and readily available. These experiments are being designed for use in the classroom or for lecture demonstrations or for use by highly motivated high school students or beginning undergraduate chemistry students. Although the use of lasers to demonstrate optical phenomena is fairly well advanced, their counterpart in chemical applications remains in a highly primitive state, even though laser techniques are revolutionizing chemical research. Funds will allow for the exploration of suitable laser chemistry experiments for the secondary school and beginning undergraduate curriculum. Simple, "hands-on" experiments will be produced for student use under the supervision and guidance of a teacher. For the most part, the science curricula of the secondary schools is in serious need of revision. This project shows the way to bringing new technologies into the secondary school chemistry program and provides a model for similar action in biology and physics programs. This project will also provide useful and current experiments for use by talented and motivated students.

将发展实验来说明激光技术在演示和理解化学原理中的应用。重点将放在氦氖激光源的使用上，这种激光源价格低廉、安全、易得。这些实验被设计用于课堂或讲座演示，或用于高度积极的高中生或刚开始的本科化学学生。尽管用激光来演示光学现象已经相当先进，但在化学方面的应用仍然处于非常原始的状态，尽管激光技术正在使化学研究发生革命性的变化。资金将允许探索适合中学和本科课程开始的激光化学实验。在老师的监督和指导下，将制作简单的“动手”实验供学生使用。在很大程度上，中学的科学课程急需修订。该项目展示了将新技术引入中学化学课程的方法，并为生物和物理课程的类似行动提供了一个模型。这个项目也将提供有用的和最新的实验，以供有才华和有动力的学生使用。
