Acquisition of a High-field Fourier Transform NMR Spectro- meter to Enhance Undergraduate Education in Chemical Spectroscopy

一台250兆赫的傅里叶变换核磁共振光谱仪正在取代一台有14年历史的60兆赫核磁共振光谱仪。新仪器易于日常使用，灵敏度更高，光谱色散更大，正在加强NMR在有机，无机和高级化学课程中的应用。此外，中级和高级化学学生的实验室经验，无论是化学专业的学生还是其他专业的学生，都被重要的新核磁共振功能所丰富。碳核磁共振正在与质子核磁共振一起成为有机化学实验室的关键成分。仪器分析和高级实验课程的学生正在利用二维核磁共振分析探索分子结构，更容易获得有意义的动力学数据，并更好地理解核磁共振实验所依据的基本原理。新仪器极大地扩展了学生自主学习的项目范围，加强了高年级本科生的研究训练。该系的课程因这些新能力的加入而变得活跃起来，其学生也为研究生学习或科学领域的就业做好了更好的准备。受资助者正在匹配非联邦来源的奖励。

A 250 MHz Fourier transform nuclear magnetic resonance spectrometer is replacing a 14-year-old 60 MHz NMR spectrometer. The new instrument's ease of routine use, much higher sensitivity, and greater spectral dispersion is enhancing use of NMR in organic, inorganic, and advanced chemistry courses. In addition the laboratory experiences of intermediate and advanced chemistry students, both chemistry majors and others, is being enriched by important new NMR capabilities. Carbon NMR is taking its place alongside proton NMR as a key ingredient of the organic chemistry laboratory. Students in instrumental analysis and advanced laboratory courses are exploring molecular structure using two-dimensional NMR analysis, obtaining meaningful kinetic data more easily, and better understanding fundamental principles upon which NMR experiments rest. The new instrument is enhancing research training of senior undergraduates by greatly extending the range of accessible projects for student independent study. The department's curriculum is being enlivened by the addition of these new capabilities, and its students are being better prepared for postgraduate study or employment in the sciences.
