Wavelength dispersive X-ray spectra with fine structures in the PIXE and PIXE-induced XRF spectra have been proved to be very much useful for chemical specification of condensed matters. The fine structures have been reproduced theoretically by introducing molecular orbital calculations, the shake-off and resonant orbital rearrangement (ROR) processes, together with the direct Coulomb interaction between projectiles and target atoms, and the self-absorption of emitted X-rays through the targets. Comparison between observed and theoretical spectra is given here for F and S atoms.
