John HOLMES

Biography

Main interests reside in the problem of assigning structures to organic cations, in the Thermochemistry (Heats of Formation, Ionization Energies and Bond Strengths) of Ions and Molecules. The laboratory contains unique apparatus for investigating ion structures and for the emission of radiation therefrom.
