An efficient approach to calculate shake-off satellite contributions to molecular Auger spectra is presented. The vertical ab initio energies of the transition to the triply ionized final states of the shake-off process are calculated by a Green's function method. An estimate of the Auger transition

โฆ Synopsis
The work of Asaad and Burhop and of Shirley on atoms is shown to form the basis of a useful theory for the xE?.!Yds of molecular core-valence-valence Auger spectra. if the static relaxation term of Shirley is neglected, the theory requires O~IY a single SCF calculation on the neutral molecule. Smce this approumation seems justified for the class of itinerant holes, the theory not only permlts the interpretation of the spectra of molecules considerably larger than previously analyzed, but potentlally the spectra of chemlsorbed molecules from cluster calculations. Theory and experiment are compared for the carbon KW spectra of CH4, CzH2. C2H4 and CHZJOH
