摘要: I have calculated ultraviolet photoionization cross sections for ${\mathrm{N}}_{2}$ and CO in the gas phase differential oriented molecules. The gas-phase results agree well with recent data display shape resonances, predicted by Dehmer Dill, about 1 Ry above threshold certain levels. For molecules find distinctive angular distributions which could be used to identify levels or determine bond geometry of adsorbed at surfaces.
