Purchase of a 100MHz FT-NMR for Undergraduate Instruction and Research

通过这个项目，该机构能够购买一台FT- NMR光谱仪，用作有机化合物结构鉴定的实验室工具。大多数化合物都是由学生在该系提供的几门有机和聚合物化学实验课程中合成的。在这个项目中，精心选择了各种实验，使学生能够欣赏和理解仪器作为结构分析的光谱工具。这些研究包括(a)聚合物的弹性分析，(b)开环聚合和闭环聚合合成的聚合物的残留单体和微观结构产物分析，(c)使用手性/非手性镧系转移试剂和酸性质子的氘交换简化一些酰胺和醇的光谱，(d)用变温核磁共振证明酰胺的旋转转化，以及(e)在合成有机化学中的普遍应用。该仪器在该系正在进行的几个学生研究项目中也很有用。该仪器提高了相关实验课程的教学质量和效果，为学生今后的化学职业生涯做了更好的准备。该机构为该项目提供的资金相当于国家科学基金会的资金。

Through this project, the institution was able to purchase an FT- NMR spectrometer to use as a laboratory tool for the structure identification of organic compounds. Most of the compounds are synthesized by students in one of several organic and polymer chemistry laboratory courses offered in the department. In this project, a variety of experiments were carefully chosen to enable the students to gain an appreciation and understanding of the instrument as a spectroscopic tool for structural analysis. These include (a) analysis of polymer tacticity, (b) residual monomer and microstructural product analysis of polymers synthesized by ring-opening and ring-closing polymerizations, (c) simplification of spectra of some amides and alcohols by use of chiral/non-chiral lanthanide shift reagents and by deuterium exchange of acidic protons, (d) demonstration of rotameric transformation in amides by variable temperature NMR, and (e) general utility in synthetic organic chemistry. The instrument has also been useful in several student research projects in progress at the department. The instrument improved the quality and effectiveness of teaching in relevant lab- associated courses and better prepared the students for advanced careers in chemistry. The institution contributed to this project in an amount equal to the NSF funds.
