在这个实验物理化学项目中，由 化学部安德森教授（纽约州立大学石溪分校）将 开发一种新的、强有力的制备多原子离子的方法 在特定的激发振动状态。具体的效果 振动激发对离子反应性，然后将研究 通过高分辨率分子束方法。的首要问题 问题是，“在什么范围内的分子大小和 振动模式效应重要吗？“一个 对这个问题的明确回答将决定未来的方向 这一领域的研究将持续多年。 %%% 将分子结合在一起的键并不是刚性的，它们是伸展的 振动物理化学长期追求的目标是 通过刺激来影响化学反应的进程 特定的振动，以便于打破特定的 债券安德森教授（纽约州立大学石溪分校）将开发一种新的 使用激光同时照射的方法 两种不同的波长。这很重要，因为 方法可以应用于更大的和更化学相关的 分子比以前可能的。

In this Experimental Physical Chemistry project, sponsored by the Chemistry Division, Prof. Anderson (SUNY Stonybrook) will develop a new and powerful method for preparing polyatomic ions in specific excited vibrational states. The effect of specific vibrational excitation on ion reactivity will then be studied by high resolution molecular beam methods. The primary question to be answered is, "in what range of molecular size and vibrational energy are vibrational mode effects important?" A clear answer to this question will determine the future course of research in this field for many years to come. %%% Bonds which hold molecules together are not rigid; they stretch and vibrate. A long sought goal of physical chemistry is to influence the course of chemical reactions by stimulating specific vibrations in order to facilitate breaking specific bonds. Prof. Anderson (SUNY Stonybrook) will develop a new method for doing this using simultaneous irradiation by lasers of two different wavelengths. This is important because the method can be applied to larger and more chemically relevant molecules than was previously possible.
