Abstract
Abstract: Mass spectrometric analysis is a key and difficult issue in teaching of spectroscopic analysis course. Moreover, fragmentation patterns are the key points for mass spectrometric analysis. Understanding the dissociation rules of organic compounds will help the students to analyze the chemical structures. From the viewpoint of teaching practice, we review in this paper the fragmentation patterns of some common isomers such as acids-esters, alcoholsethers, and straight-chain and branched-chain alkyl groups. In addition, some classic examples were presented to help the students to grasp the fragmentation patterns as well as to improve their ability of mass spectrometric analysis.
