摘要： 在本科实验教学中引入仪器搭建的教学内容，是对仪器分析实验课程教学改革的新挑战。实验中，学生自主设计并亲手搭建拉曼光谱仪，通过更换不同规格的光学元件和实验参数，系统探究影响仪器检测技术指标的各种因素。使用自主搭建的拉曼光谱仪进行氨基酸的检测鉴别，掌握拉曼光谱用于分子结构分析的方法。本实验对标化学“101计划”课程设计要求，强调过程参与的实践教学模式，在激发学生学习兴趣的同时，注重培养学生的科学探究精神，强化理论和实践的联系。

Abstract: The application of self-constructed instruments in experimental teaching presents a new challenge in the reform of instrumental analysis experiment courses. In these experiments, students independently design and construct Raman spectrometers. By replacing optical components of different specifications and adjusting experimental parameters, students systematically explore various factors affecting the technical performance of the instruments. They utilize the self-constructed Raman spectrometers to detect and identify amino acids, mastering the method of using Raman spectroscopy for molecular structural analysis. This experiment aligns with the requirements of the chemistry “101 Plan” course design, emphasizing the practical teaching mode of process participation. While stimulating students' interest in learning, it focuses on cultivating their scientific exploration spirit and strengthening the connection between theory and practice.
