The Department of Chemistry is purchasing a 300 MHz broadband NMR spectrometer with variable temperature capabilities for the use of undergraduate instruction. The instrument is an vital component in the implementation of a innovative long range undergraduate laboratory project extending over the two years of instruction in organic and physical chemistry. Known locally as a series experiment the students synthesize a porphyrin in the organic laboratory and study many of its chemical and physical properties. They retain a sample of the prepared compound for use in further courses. For example, in physical chemistry they acquire 2-D spectra and investigate the tautomeric forms of porphyrins. These experiments are followed by conversion to both a diamagnetic and paramagnetic metalloporphyrin which is investigated using both NMR and EPR techniques.

化学系正在购买一台300 MHz宽带NMR光谱仪，具有可变温度功能，供本科教学使用。 该仪器是一个创新的远程本科实验室项目的实施，在有机和物理化学教学的两年时间延长的重要组成部分。 学生们在有机实验室合成卟啉，并研究其许多化学和物理性质。 他们保留了一份制备好的化合物样品，以供进一步的课程使用。 例如，在物理化学中，他们获得二维光谱并研究卟啉的互变异构形式。 这些实验之后，转换为抗磁性和顺磁性金属卟啉，这是使用NMR和EPR技术进行研究。
