Multiresonant Spectroscopy of Long-Range States of Molecular Hydrogen

分子中高激发态的结构和衰变动力学是一个研究领域，它为阐明物理学提供了丰富多样的样本。氢分子是最简单的稳定中性分子，是探测分子中基本量子力学效应的一个特别重要的系统。一个戏剧性的例子是一类所谓的双阱态，它们的尺寸非常大。 这些分子构型的结构和动力学一直是科学家们感兴趣的，但它们的性质使它们非常难以创造和研究。 PI已经开发了一种新的激发方案，这将使我们能够前所未有地获得氢分子中的这些奇异状态。 实验测量的结果将提供一个重要的激励发展的改进方法计算的结构？超级兴奋必须考虑内能超过电离和解离阈值以及大范围分子尺寸的分子构型。这些结果将为氢分子高激发态的动力学及其在许多天文和大气过程中的重要作用提供新的信息。这项研究计划将在布林莫尔学院进行，并将为年轻妇女提供一个机会，以获得深入的实验室研究经验。 在研究中，这个在物理学中代表性不足的群体的成员将建立导师关系，并探索可以支持他们在物理科学中的坚持和成功的职业期望。

The structure and decay dynamics of highly excited states in molecules is a research area that has provided a rich and diverse sampling of elucidating physics. The hydrogen molecule, being the simplest stable neutral molecule, is an especially important system for probing fundamental quantum mechanical effects in molecules. A dramatic example is a class of so-called double-well states of unusually large size. The structure and dynamics of these molecular configurations have long been of interest to scientists, but their nature has made them very difficult to create and study. The PI has developed a new excitation scheme that will allow us unprecedented access to these exotic states in molecular hydrogen. The results of the experimental measurements will provide an important incentive for the development of improved methods of calculating the structure of ?super-excited? molecular configurations where internal energies exceed ionization and dissociation thresholds and large ranges of molecular size must be considered. The results will provide new information about the dynamics of highly excited states of molecular hydrogen and their important role in many astronomical and atmospheric processes. This research program will be conducted at Bryn Mawr College and will provide young women an opportunity to obtain in-depth laboratory research experiences. Engaged in research, members of this underrepresented group in physics will build mentor relationships and explore career expectations that can support their persistence and success in the physical sciences.
