Abstract:

The goals of this theoretical research are 1 to determine a more accurate and consistent theoretical model of the excitation, emission, and deactivation properties of the N2 molecular band systems excited by electrons 2 determine a consistent set of electron impact excitation cross sections for the electronic states of N2 over the range of incident electron energies that is relevant to understanding and predicting atmospheric processes 3 with these excitation cross sections, perform the theoretical studies necessary to obtain a better understanding of the excitation, emission, and deactivation properties of the various N2 band systems excited in the normal and disturbed atmosphere. The following are discussed the Meinel band system of N2 theoretical work leading to study of autoionization electron-impact excitation of electronic states of N2 and, quadrupole moment and electric field gradient of N2 X singlet Sigmag.
