摘要
The vacuum ultraviolet photoionization spectrum of Si(CH3)2Cl2 has been obtained with synchrotron radiation source. The adiabatic iomzation potential of Si(CHa)2Cl2 is 10.62±0.03eV (0.37eV lower than reported by PES), and the appearance potentials for Si(CH3)Cl2, Si(CH3)2Cl+, SiCH3+ and SiCl+ are 11.25±0.03eV,12.69±0.04eV, 15. 1±0.1eV and 21.16eV±0.1eV respectively. From these results, we estimate D(Si(CH3)Cl2+-CH3)=0.631±0.03eV and D(Si(CH3)2Cl+-Cl))=2.07±0.04eV.
