Abstract:

Nuclear Magnetic Resonance (NMR) is a common method to analyze the structure of organic compounds, and it is also one of the important contents in the course of organic spectrum analysis. This paper introduces the idea of ¹H NMR analysis, combining theory with three examples of scientific research practice, using ¹H NMR to identify the structure of isomers in organic synthetic products, and determine the proportion of isomers by the integral area of peak group, in order to cultivate students' scientific literacy, stimulate students' interest in learning and improving the ability of spectrum analysis.

Key words: ¹H NMR spectroscopy, Isomers, Chemical shifts, Coupling constants, Structural analysis
