摘要:

αβ-不饱和羰基化合物K带位置计算是谱学导论课程中紫外-可见吸收光谱这一章的重点和难点,在教学中发现学生在计算过程中总是出现种种问题,很难得到正确的结果。本文对αβ-不饱和羰基化合物K带位置的计算方法以及注意事项进行了详细的介绍,并通过具体实例进一步说明,力图帮助学生掌握αβ-不饱和羰基化合物K带位置计算的问题。

关键词: α, β-不饱和羰基化合物, K带位置, 计算方法, 注意事项

Abstract:

Calculation of K-band position of α, β-unsaturated carbonyl compounds is the key and difficult point in the chapter of Ultraviolet-Visible Absorption Spectroscopy in Introduction to Spectroscopy. In teaching, it is found that students always have various problems in the process of calculating K-band position, so it's hard for students to get the right results. This paper gives a detailed introduction to the calculation method and matters needing attention, where are further illustrated by examples. We will try to help students learn and master the problem of K-band position calculation.

Key words: α, β-Unsaturated carbonyl compounds, K-Band position, Calculation method, Matters needing attention
