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

在化学学部物理化学项目中，Dickinson College化学系Cindy Samet教授将对烃基配合物中缩合相的氢键进行研究。这项工作的目的是研究C-H氢键及其对碳的s和p轨道杂化的依赖，以及对吸电子成分的存在的依赖。进行这项工作的主要技术是矩阵分离傅立叶变换光谱。这个研究项目也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师作为独立研究科学家的首次亮相。氢键表示强结合分子之间形成弱结合复合物的相互作用。连接剂是质子供体分子的一个氢原子质子，它与伙伴质子受体分子形成弱键。氢键在有机材料，包括生物材料的结构和键合中起着重要作用。这项研究的初步研究将在更大的系统上进行，如有机晶体和大型生物分子。迪金森学院的化学课程最近进行了修订，现在包含了研究作为化学专业的必修课程。这个项目将加强本科化学课程，从而有助于提高下一代科学家的教育水平。

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.
