Description
Mass Spectrometry of Organic Ions covers the underlying theories and major applications of mass spectrometry.
This 13-chapter book starts with a survey of the mechanisms by which organic ions can decompose and rearrange, as well as the generalized concept in terms of physical-organic chemistry. The discussion then shifts to the advantages and potential of mass spectrometry in structure determination by the elucidation of the empirical formulas of organic ions. Considerable chapters are devoted to the detailed correlations and mechanisms of the mass spectra of long-chain esters, alkylbenzenes, a variety of natural products, aliphatic compounds, and terpenes. The remaining chapters demonstrate the illustrative power of mass spectrometry in structure of petroleum, which is composed of hydrocarbon mixture.
This book will be of great benefit to organic and analytical chemists, scientists, and students.
