In this project funded by the Chemical Structure, Dynamics, and Mechanisms Program of the Division of Chemistry, Professor Jochen Autschbach of the University at Buffalo, State University of New York, and his research team are developing and applying theoretical models to describe how molecules interact with light. Professor Autschbach is investigating how molecules interact simultaneously with magnetic fields and electromagnetic radiation. This phenomenon occurs in a chemical measurement technique called nuclear magnetic resonance (NMR), which is related to magnetic resonance imaging (MRI) used in modern medicine. He is also studying how molecules and their mirror-image counterparts interact with light and how the environment around a molecule influences its interaction with light. Such properties are frequently measured in order to deduce information about the structures and functions of molecules, and theoretical support is needed to help establish these relationships. Professor Autschbach is making available the theoretical methods and software developed during this investigation to the larger community of scientists. This research project provides an in-depth training of graduate and undergraduate students as well as an opportunity for high school students to experience a summer internship. The graduate and undergraduate student experience is being enhanced by the collaborative nature of the project, because the project is being carried out in collaboration with experimentalists from a variety of fields, including materials science and catalysisQuantum-theoretical methods are being developed to understand how molecular structure and dynamics influence a variety of molecular optical and spectroscopic properties. Such properties are frequently measured in order to deduce information about the structures and functions of molecules, and theoretical support is needed to help establish these relationships. Specifically, the parameters being addressed in this project include determining the NMR response and the optical activity of molecules. The calculations focus on NMR relaxation phenomena and on the structural and electronic origins of natural electronic and vibrational optical activity. In addition, the influence of the chemical and physical environment on these molecular properties is being explored.

在这个由化学系化学结构、动力学和机制计划资助的项目中，纽约州立大学布法罗大学的Jochen Autschbach教授和他的研究小组正在开发和应用理论模型来描述分子如何与光相互作用。 Autschbach教授正在研究分子如何同时与磁场和电磁辐射相互作用。 这种现象发生在一种称为核磁共振（NMR）的化学测量技术中，它与现代医学中使用的磁共振成像（MRI）有关。 他还在研究分子及其镜像对应物如何与光相互作用，以及分子周围的环境如何影响其与光的相互作用。 这些性质经常被测量，以推断分子的结构和功能的信息，需要理论支持来帮助建立这些关系。 Autschbach教授正在向更大的科学家社区提供在这次调查中开发的理论方法和软件。 该研究项目为研究生和本科生提供了深入的培训，并为高中生提供了暑期实习的机会。 研究生和本科生的经验正在通过该项目的合作性质得到加强，因为该项目正在与来自各个领域的实验学家合作进行，包括材料科学和催化量子理论方法正在开发，以了解分子结构和动力学如何影响各种分子光学和光谱特性。 这些性质经常被测量，以推断分子的结构和功能的信息，需要理论支持来帮助建立这些关系。 具体而言，该项目中涉及的参数包括确定分子的NMR响应和光学活性。计算集中在NMR弛豫现象和天然电子和振动光学活性的结构和电子起源。此外，化学和物理环境对这些分子特性的影响正在探索中。
