Modernization of Undergraduate Curriculum through Laser - Based Spectroscopies

化学系正在积极追求其教学实验室的现代化，通过提供现代仪器的实践经验。 作为努力更新整个本科课程的一部分，该部门正在将物理化学和仪器分析实验室的实验室组成部分结合到一个为期一年的高级实验室中。 新设备显著影响学生在这门课程中的体验。 国家的最先进的仪器正在使用的Nd：YAG泵浦染料激光器和飞行时间（TOF）质谱仪在各种实验。这些实验被选择来说明讲座中讨论的主题，并通过让学生接触当前的研究主题和方法来保持学生的兴趣和热情。 该项目的新颖之处在于将基于激光的综合方法用于高级实验室，生物分子的飞行时间质谱法作为学生积累经验的顶峰。 具体的基于激光的实验包括Fe（CO）s的光解离、使用TOF质谱仪的Fe原子的非线性原子光谱和CHCl 3的拉曼光谱。 学生们随后将基于激光的光谱技术应用于无机化学和生物化学。 此外，鼓励学生将这些技术应用于传统化学部门选择的原创研究项目，包括物理，分析，无机和生物化学。

The Department of Chemistry is actively pursuing the modernization of its teaching laboratories by providing hands-on experience with modern instrumentation. As a part of the effort to update the entire undergraduate curriculum, the department is combining the laboratory components of physical chemistry and instrumental analysis laboratories into a year-long Advanced Laboratory. New equipment is significantly affecting the students' experience in this course. State-of-the-art instruments are being used an Nd:YAG pumped-dye laser and a time-of-flight (TOF) mass spectrometer in a variety of experiments. These experiments are being selected to illustrate topics discussed in lectures and to maintain students' interest and enthusiasm by exposing them to current research topics and methodologies. The novel aspect of this project is the use of an integrated laser-based approach to upper-division experimental laboratories, with time-of-flight mass spectrometry of biomolecules serving as the capstone of the students' accumulated experiences. Specific laser-based experiments include photodissociation of Fe(CO)s, nonlinear atomic spectroscopy of Fe atoms using a TOF mass spectrometer, and Raman spectroscopy of CHCl3. The students are subsequently applying laser-based spectroscopy techniques in inorganic chemistry and biochemistry. In addition, students are being encouraged to apply these techniques in original research projects chosen across the traditional divisions of chemistry including, physical, analytical, inorganic, and biological chemistry.
