Applications of FT-NMR throughout the Undergraduate Chemistry Laboratory Curriculum

化学系致力于扩大核磁共振波谱作为一种工具的使用，以丰富本科生在化学课堂上的实验室经验。正在开发的实验模块允许学生在各种课程中获取、解释和报告他们自己的核磁共振数据。这些模块是根据文献中的实验进行调整的，主要是在《化学教育杂志》上。首先，我们正在开发将核磁共振应用于化学专业所需实验室的模块。然后，我们将应用程序扩展到化学专业序列中较早出现的实验室和非专业实验室。我们打算让这些基于核磁共振的实验成为教授科学的实验方法的例证，以便学生发展理解数据获取和分析所需的技能。此外，现代核磁共振仪器和相关计算机设备的使用有望激发非专业学生对化学的兴趣。为了实施这一项目，我们的光谱仪正在升级，配备了一个新的控制台，并配备了100个样品转换装置。我们最近将这台光谱仪专门用于支持本科教育，并于最近将其重新安置，以便于使用。通过样品转换器升级，我们可以让光谱仪在夜间自动获取数据，从而获得多达100名学生的实验室光谱，而不会占用宝贵的实验室时间。我们正在计划申请有机、无机、仪器、生物化学和定量分析实验室课程，以及两个较低水平的非专业班级。该学院招收了大量来自代表性较低的少数族裔的学生，这些学生从参与这个项目中受益。此外，该项目还包括与芝加哥少数族裔参与联盟(CHAMP)的直接互动，通过使用核磁共振来支持该系CHAMP学者的本科生研究，并且该核磁共振也被用作CHAMP努力的一部分，该努力正在重组入门学生的介绍性实验室。我们致力于最大限度地传播我们的工作。为此，我们计划广泛使用互联网，并正在建立页面，展示学生在各个实验室获得的数据。其他机构可能会下载这些数据，并在本地进行处理和分析。

The Chemistry Department is committed to expanding the use of NMR spectroscopy as a tool to enrich the laboratory experiences of students in undergraduate chemistry classes. Experimental modules are being developed that allow the students to obtain, interpret, and report on their own NMR data in a variety of courses. The modules are adapting experiments found in the literature, largely in the Journal of Chemical Education. First, we are developing modules that apply NMR to laboratories which are required for chemistry majors. We then expand the applications to laboratories that occur earlier in the chemistry major's sequence and to laboratories for non-majors. We intend for these NMR-based experiments to exemplify an experimental approach to teaching science so that students develop the skills needed to understand data acquisition and analysis. In addition, the use of modern NMR instrumentation and related computer equipment is expected to stimulate the interest of non-majors in chemistry.In order to carry out this project, our spectrometer is being upgraded with a new console and is being equipped with a 100-sample sample-changer device. We recently dedicated this spectrometer to supporting undergraduate education and recently relocated it to facilitate that use. With the sample-changer upgrade we can obtain spectra for labs with up to one hundred students by letting the spectrometer acquire the data under automation during overnight time, without taking up valuable lab time to do so. We are planning applications to organic, inorganic, instrumental, biochemistry and quantitative analysis laboratory courses, as well as to two lower level non-majors classes.The institution has a high enrollment of students from underrepresented minorities, and those students are benefitting from participation in this project. In addition, this project includes direct interaction with the Chicago Alliance for Minority Participation (ChAMP) by using the NMR to support undergraduate research by ChAMP scholars in the department, and the NMR also is being used as part of a ChAMP effort that is restructuring introductory laboratories for entering students. We are committed to maximizing dissemination of our work. To this end we are planning extensive use of the internet, and pages are being set up that present data obtained by students in the various labs. Other institutions may download that data and process and analyze it locally.
