Auger-electron spectra of F3SiCH2CH2Si(CH3)3 obtained by using monochromatized synchrotron radiation

A study on Auger-electron spectra of F3SiCH2CH2Si(CH3)3 was performed by using monochromatized synchrotron radiation. The normal Si:L23VV Auger-electron spectrum was measured in the vapor phase and characterized through the ab initio molecular orbital calculation. The cascade Si:L23VV Auger-electron spectra were also obtained by L23-holes creation through Si:KL23L23 Auger transitions after Si:1s photoexcitation in the vapor phase or its photoelectron emission in the condensed phase. Further the C:KVV and F:KVV Auger-electron spectra were measured and discussed in comparison with those of some related molecules.
