An NMR Spectrometer to Support a General Chemistry Peer Mentoring Program

化学（12）本项目的目标是为使用有机化学学生作为同伴导师的普通化学实验室开发一系列有机化学/光谱学实验。在小组工作中，普通化学的学生进行探究实验，介绍他们的紫外可见光，红外光谱和核磁共振光谱。实验结束后，有机化学同伴指导小组利用电子邮件、网络讨论板等电子工具与普通化学学生进行在线协作，帮助普通化学学生应用新学到的知识。该项目的这一部分改编自物理化学在线项目（NSF DUE-9950809）。由于C-13谱的相对简单，我们介绍了NMR与C-13，而不是质子谱。我们现有的Varian EM 360与Anasazi EFT-GENII FT-NMR转换包的升级提供了一个仪器，使我们能够做质子和C-13光谱。我们还在有机化学和高级有机化学课程中使用这种光谱仪，并正在改编《化学教育杂志》的实验，使学生能够分组工作。升级后的NMR完成了一套仪器，我们介绍我们的本科生在他们的职业生涯的早期点。它还使我们能够建立一个同行指导计划，我们希望这将提高我们的学生的沟通能力，使有机化学更有吸引力的学生谁已经完成了普通化学。该项目作为有机化学同行导师如何在普通化学中使用的一个模型。我们也正在开发新的实验，介绍核磁共振入门学生。

Chemistry (12)The goal of this project is to develop a series of organic chemistry/spectroscopy experiments for the general chemistry laboratory that use organic chemistry students as peer mentors. Working in groups, the general chemistry students work on inquiry experiments that introduce them to UV-visible, IR, and NMR spectrometry. Using electronic tools such as e-mail and Web-based discussion boards, organic chemistry peer mentor groups collaborate on-line with the general chemistry students after the experiments, which helps the general chemistry students apply their newly learned knowledge. This portion of the project is adapted from the Physical Chemistry On-line project (NSF DUE-9950809). Because of the relative simplicity of C-13 spectra, we introduce NMR with C-13 rather than proton spectra. An upgrade of our existing Varian EM360 with an Anasazi EFT-GENII FT-NMR conversion package provides an instrument that allows us to do both proton and C-13 spectra. We also are using this spectrometer in our organic chemistry and advanced organic chemistry courses, and are adapting experiments from the Journal of Chemical Education that allow students to work in groups. The upgraded NMR completes the suite of instruments to which we introduce our undergraduate students at an early point in their careers. It also allows us to institute a peer-mentoring program, which we expect will enhance our students' communication skills and make organic chemistry more attractive to students who have finished general chemistry. The project serves as a model of how organic chemistry peer mentors can be used in general chemistry. We also are developing new experiments that introduce NMR to introductory students.
