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.
几种同分异构体质谱分析的探讨
摘要:质谱分析是光谱分析课程教学的重点和难点。此外,碎片模式是质谱分析的关键点。了解有机化合物的解离规律有助于学生分析其化学结构。本文从教学实践的角度,综述了一些常见的同分异构体,如酸酯、醇醚、直链和支链烷基的断裂模式。此外,还列举了一些经典的例子,帮助学生掌握碎片模式,提高他们的质谱分析能力。
