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
