Abstract:

Chemielectron spectroscopy has been used to study the associative and rearrangement ionization reactions of a number of metals with 0, 02X 3g - and O2al A g and other atmospheric species. The spectra obtained have been used to identify the main chemiionization channel and to obtain details of the potential surfaces of the reactants and products. Mass spectra, recorded as a function of extraction potential, have also been used to identify primary ions associated with chemiionization reactions. The chemiionization reactions of oxygen atoms with a number of hydrocarbons have also been studied by chemielectron spectroscopy. Photoelectron spectroscopy has also been used to study in the gas phase the electronic structure of a number of metals and metal oxides which are of importance in the upper atmosphere. Multiphoton spectroscopic studies have also been performed on a number of reactive intermediates.
