Reactant State-Selection and Product Energy Disposal in Polyatomic Ion-Molecule Reactions

在这个由化学部赞助的实验物理化学项目中，Anderson教授（SUNY Stonybrook）将开发一种新的强大的方法来制备具有特定激发振动态的多原子离子。然后用高分辨率分子束方法研究特定振动激发对离子反应性的影响。要回答的主要问题是，“在分子大小和振动能量的什么范围内，振动模式效应是重要的？”这个问题的明确答案将决定未来许多年这一领域的研究方向。将分子连接在一起的键不是刚性的；它们伸展和振动。物理化学长期追求的目标是通过刺激特定的振动来影响化学反应的过程，从而促进特定键的断裂。安德森教授（纽约州立大学石溪分校）将开发一种新方法，使用两种不同波长的激光同时照射。这很重要，因为该方法可以应用于比以前更大、更化学相关的分子。

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.
