Angular distribution of photoelectronic spectra of molecules in independent atom centers approximation

The asymmetric parameters of the photoelectronic spectra of the N/sub 2/, CO/sub 2/, N/sub 2/, N/sub 2/O, CF/sub 4/, HCl, and Cl/sub 2/ molecules were calculated for photon energies of h nu less than or equal to 70 eV. It was found that the independent atomic centers approximation can be used for calculating the asymmetry parameters and for interpreting the photoelectronic spectra of the molecules according to an angular dependence in the energy regions where there are no form resonances in the photoionization cross sections.
