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确定物质的化学特性至关重要。化学教师正在从多个来源进行调整实验，并增强了化学计划课程，包括动手光谱仪器，即核磁共振，NMR（1H和13C）以及红外光谱仪，FT-IR。在各个级别的化学课程中纳入光谱学会鼓励学生在学术职业早期学习科学工具的适当处理，以发展分析，解决问题和批判性思维能力，以转移到四年制机构。一般化学和非硕士学生学会识别官能团，区分结构异构体并确定产品结构。有机化学的学生使用这些仪器来表征合成产品的结构，立体化学从耦合常数确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验室课程中的光谱学纳入实际观察的技能。为高中科学教师提供的光谱讲习班为他们提供专业发展和继续教育的机会。这鼓励化学老师将光谱学主题纳入高中课程。
