Abstract: 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.
