Beschreibung

A guide to CIMS applications in structural elucidation and analytical studies. It discusses such topics as reagent ion systems within the context of the thermochemistry and kinetics of the ionization process, including reactions and the type of information obtained; isotopic exchange reactions; and, stereochemical effects in chemical ionization.
