Opis

Assigning Structures to Ions in Mass Spectrometry describes the tools currently available for determining gas-phase ion structures. It surveys current experimental methods for ion production and separation as well as those designed to reveal qualitative and quantitative aspects of gas-phase ions. It also examines how and when to apply computational

Recenzje

"There is no comparable combination of an in-depth discussion and a comprehensive compendium of thermochemical data of organic ions. … warmly recommended to all scientists who are interested and/or work in fields connected with mass spectrometry. … warmly recommended to all scientists who are interested and/or work in fields connected with mass spectrometry. … I recommend it for all who look at mass-spectral peaks— whatever m/z—with curiosity!"
