Dr. John Holmes

John L. Holmes' work on the kinetics and energetics of gas-phase reactions of organic ions has made him a leader in this field. His development of new methods for measuring the release and partitioning of energy in ionic fragmentations, from the detailed shapes of metastable ion peaks, has provided by far the most quantitative measures of these important quantities. A critical survey of the data for the heats of formation or organic ions has led him to formulate general rules for assessing and predicting ionic heats of formation, a scheme that complements that for neutral compounds.
