Theoretical Determination of Metal Oxide f-Numbers
Abstract
The release of certain chemical species into the upper atmosphere results in luminous clouds that display the resonance electronic-vibrational- rotation spectrum of the released species. Such spectra are seen in rocket releases of chemicals for upper atmospheric studies and upon reentry into the atmosphere of artificial satellites and missiles. Of particular interest in this connection is the observed spectra of certain metallic oxides. From band intensity distribution of the spectra, and knowledge of the f-values for electronic and vibrational transitions, the local conditions of the atmosphere can be determined. Calculations have been performed for band-to-band transition probabilities. The systems under study were LiO, AlO, FeO, UO(+), UO and TiO. Electronic wave-functions have been constructed for selected states of these molecules and expectation values of the electronic energy and electric dipole transition moments have been calculated.
