Infrared Matrix Isolation Studies of Cyclic Hydrocarbons with Nitrogen and Oxygen Bases

在化学系物理化学项目的这个项目中，狄金森学院化学系的Cindy Samet教授将致力于研究凝聚相中烃基络合物中的氢键。这项工作的目的是研究C-H氢键及其对碳的S轨道和p轨道杂化的依赖关系，以及吸电子组分的存在。进行这项工作的主要技术是矩阵隔离傅里叶变换光谱。这项研究项目还将增加狄金森学院本科生的研究机会。这个项目代表了一位年轻的女教员作为一名独立研究科学家的首次亮相。氢键代表强结合分子之间的相互作用，形成弱结合络合物。连接剂是一个分子的氢原子质子，它是质子供体，它与伙伴质子受体分子形成弱键。氢键在有机材料的结构和结合中起着重要的作用，包括那些具有生物重要性的材料。这项研究的初步研究将在有机晶体和大生物分子等较大系统的工作基础上进行。迪金森学院的化学课程最近进行了修订，现在将研究作为化学专业的必修课。该项目将加强本科生的化学课程，从而有助于改善对下一代科学家的教育。

In this project in the Physical Chemistry Program of the Chemistry Division, Professor Cindy Samet of the Chemistry Department of Dickinson College will engage in a study of the hydrogen bonding in hydrocarbon-base complexes in the condensed phase. The goal of the work is to investigate the C-H hydrogen bonding and its dependence on the hybridization of the s and p orbitals of the carbon, and on the presence of electron withdrawing constituents. The principal technique for carrying out this work is matrix isolation Fourier transform spectroscopy. This research project will also enhance the research opportunities for undergraduate students at Dickinson College. This project represents the debut of a young woman faculty member as an independent research scientist. Hydrogen bonding represents an interaction between strongly bound molecules which form a weakly bound complex. The linking agent is a hydrogen atom proton of one molecule, the proton donor, which forms a weak bond with the partner, the proton acceptor molecule. Hydrogen bonding plays an important role in the structure and bonding of organic materials, including those of biological importance. The initial studies of this research will be followed up with work on larger systems such as organic crystals and large biomolecules. The chemistry curriculum of Dickinson College has recently been revised and now contains research as a requirement for chemistry majors. This project will strengthen the undergraduate chemistry curriculum and thereby contribute to an improved education of the next generation of scientists.
