摘　　要：在分析化学教材中简要介绍电子跃迁光选律的相关内容,是对选择性吸收知识点的有益补充,有助于学生更全面地理解电子吸收光谱产生的原理,符合当前分析化学发展趋势,也符合以选拔培养基础学科拔尖创新人才为目标的国家强基计划所需。考虑到本科生一或二年级的数理水平,以及鉴于部分学生此后可能不再接触到电子吸收光谱的基本理论方面的知识,建议在化学分析和仪器分析课程中分层次引入电子吸收光谱光选律的内容。并建议只作定性的、非数学化描述,同时提供更深入的阅读资料,以便于学习的可持续性。t A brief introduction to the photoselection rule of electron transition in analytical chemistry textbooks is a favorable supplement to the knowledge points of selective absorption in current textbooks.It is beneficial for students to have a more comprehensive understanding of the principles of electron absorption spectroscopy,which is in line with the current development trend of analytical chemistry and also meets the needs of the national consolidation foundation programs aimed at selecting and cultivating top-creative-talents in basic disciplines.Considering the mathematical and physical proficiency of undergraduate students in their first or second year,as well as the possibility that some students may no longer be exposed to the basic theoretical course of electron absorption spectroscopy in the future university studies,it is suggested to introduce the photoselection rules of electron absorption spectroscopy in chemical analysis and instrumental analysis courses in a hierarchical manner.And it is recommended to provide only qualitative and non-mathematical descriptions,while also providing further reading materials for the sustainability of learning.
