  Site‐specific fragmentation following Si:2pcore‐level photoexcitation of F₃SiCH₂Si(CH₃)₃in the vapor phase

  摘要：

  Site-specific fragmentation following Si:2p photoexcitation of (trifluorosilyl) (trimethylsilyl)methane [F3SiCH2Si(CH3)3 (FSMSM)] has been studied by means of photoelectron-photoion and photoion–photoion coincidence techniques. The total photoionization efficiency curve of FSMSM has only one broad peak near the Si:2p core-ionization threshold and no evidence is obtained for the occurrence of selective excitation of each of the two Si atoms. From the results of ab initio calculations of FSMSM, it is found that the magnitude of the Coulomb interaction between the valence electrons and the Si:2p core electrons is very similar at the two Si sites. As a result, the difference in the chemical shift of the 2p core level between the two Si sites is very small. However, the evidence for site-specific fragmentation of the molecule following the Si:2p core-level photoexcitation is obtained by analyzing the photoion–photoion coincidence spectra; the relative yields of H+–SiF+ and CH+n–SiF+3 (n=1–3) ion pairs are enhanced around 104.5 eV, and those of CH+3–F3SiCH2Si(CH3)+2, CH+3–SiCH3F+2, CH+3–Si(CH3)2F+, and H+–SiCH+3 are enhanced around 107 eV. These two thresholds are interpreted to correspond to the 2p core-level photoexcitation at the Si atom bonded to three F atoms and that at the Si atom bonded to three CH3 groups. Ionic fragmentation following excitation of these core electrons occurs selectively around the Si atom where the photoexcitation has taken place. The site-specific fragmentation scheme can be explained on the basis of the valence electron density around the excitation site.
