摘　　要：结合计算化学,对现有的物理化学实验教材中的“偶极矩测定”实验进行拓展,通过势能曲线探究乙酸乙酯的可能结构,并将偶极矩计算与结构相联系,同时考虑不同条件对偶极矩计算结果的影响。实验能够从微观角度对宏观现象进行辨析,并帮助理解结构与性质之间的关系。整个实验坚持“教-学-评”一体化,实验设计与课程思政有机融合,通过案例分享、知识探究,可有效激发学习兴趣和热情,培养思辨的科学研究能力。This study integrates computational chemistry to expand the traditional dipole moment measurement experiment found in physical chemistry textbooks.The potential energy curve is used to investigate possible structures of ethyl acetate,and the dipole moment is linked to these structures.Additionally,the impact of various conditions on the dipole moment calculation is explored.This approach allows for a microscopic analysis of macroscopic phenomena,aiding in the understanding of the relationship between molecular structure and properties.The experiment is designed with an integrated teaching-learning-evaluation framework and aligns with the principles of curriculum-based ideological and political education.Through case studies and knowledge exploration,the experiment effectively stimulates students’interest and fosters critical scientific research skills.
