Chemistry (12)Spectroscopic analysis of compounds, critical for the comprehension of how molecular structure determines the chemical properties of matter, is used extensively in chemistry. The Chemistry faculty are adapting experiments from multiple sources and are enhancing the chemistry program curricula to include hands-on spectroscopic instrumentation, namely nuclear magnetic resonance, NMR (1H and 13C), and infrared spectroscopy, FT-IR. The inclusion of spectroscopy at all levels of chemistry classes encourages students to learn proper handling of scientific instruments for data collection early in their academic careers, developing analytical, problem solving, and critical thinking skills necessary for transfer to four-year institutions. The general chemistry and the non-major students learn to identify functional groups, differentiate between structural isomers, and determine product structures. Students in organic chemistry use these instruments for structure characterization of synthesized products, stereochemistry determination from coupling constants, and identification of unknown organic compounds. Above all, our students are developing the skills to relate theoretical concepts to practical observations with the inclusion of spectroscopy in the laboratory curriculum. Spectroscopy workshops for high school science teachers are being held to provide them with professional development and continuing education opportunities. This encourages chemistry teachers to incorporate topics on spectroscopy into the high school curriculum.

化学(12)化合物的光谱分析，对于理解分子结构如何决定物质的化学性质至关重要，在化学中被广泛使用。化学系正在调整来自多个来源的实验，并正在加强化学课程课程，以包括实际操作的光谱仪器，即核磁共振、核磁共振(1H和13C)和红外光谱、FT-IR。在所有级别的化学课程中加入光谱学，鼓励学生在他们的学术生涯早期学习正确处理用于数据收集的科学仪器，发展必要的分析、解决问题和批判性思维技能，以便转到四年制院校。普通化学和非主修专业的学生学习识别官能团、区分结构异构体和确定产品结构。有机化学专业的学生使用这些仪器来表征合成产物的结构，根据偶合常数进行立体化学测定，以及鉴定未知的有机化合物。最重要的是，我们的学生正在发展将理论概念与实际观察联系起来的技能，并将光谱学纳入实验室课程。正在为高中科学教师举办光谱学讲习班，为他们提供专业发展和继续教育的机会。这鼓励化学教师将光谱学的主题纳入高中课程。
