Molecular charge-transfer cross sections and their correlation with reactant ion structures

Charge-transfer cross sections have been obtained by using time-of-flight techniques, and results correlated with reaction energetics and theoretical structures computed by self-consistent field-molecular orbital methods. Ion recombination energies, structures, heats of formation, reaction energy defects, and 3.0-keV charge-transfer cross sections are presented for reactions of molecular and fragment ions produced by electron bombardment ionization of CH30CH, and CH{\$}l molecules. Relationships between experimental cross sections and reaction energetics involving different ion structures are discussed
