“…Each of those peak groups is seen to be further split into two components, which come from spin–orbit coupling. The binding energies of Si[X]: and Si[Me]:2p electrons in FSMSE and CSMSE vapors have already been reported (ref and Table S1 of ref ).…”

Site-specific electron relaxations caused by Si:2p core-level photoionizations in FSiCHCHSi(CH) and ClSiCHCHSi(CH) vapors have been studied by means of the photoelectron Auger electron coincidence spectroscopy. FSiCHCHSi(CH) shows almost 100% site-specificity in fragmentation caused by the Si:2p ionization. However, substitution of Cl for F of FSiCHCHSi(CH) considerably reduces the site-specificity at the Si atom bonded to three halogen atoms, with the site-specificity at the Si site bonded to three methyl groups remaining largely unchanged. The site-specificity reduction in ClSiCHCHSi(CH) is considered to take place during the transient period between Si:LVV Auger electron emission and the subsequent fragmentation. The reason for the reduction can be explained in terms of some differences between these two molecules in the LVV Auger decay at the Si site bonded to the three halogen atoms.

“…(a) FSMSE vapor. Calibration of the binding-energy scale has been performed using a high-resolution Si:2p PES reported previously . The intensity ratios between the 2p 3/2 and 2p 1/2 photoelectrons seen in this figure are 2.0:1.0 and 2.0:1.5 at the Si[Me] and Si[F] sites, respectively.…”

“…The spectra shown in Figure 1 and all the PES given in this paper are plotted as a function of the photoelectron binding energy. The PES of FSMSE has two peaks, and the peaks at lower and higher binding energies are respectively assigned to the Si[Me]:2p and Si[F]:2p core-ionized states, whose energies 38 and the difference between them are given in Table S1 (Supporting Information) together with those of the other HSMSB.…”

A Study To Control Chemical Reactions Using Si:2p Core Ionization: Site-Specific Fragmentation

In an aim to create a "sharp" molecular knife, we have studied site-specific fragmentation caused by Si:2p core photoionization of bridged trihalosilyltrimethylsilyl molecules in the vapor phase. Highly site-specific bond dissociation has been found to occur around the core-ionized Si site in some of the molecules studied. The site specificity in fragmentation and the 2p binding energy difference between the two Si sites depend in similar ways on the intersite bridge and the electronegativities of the included halogen atoms. The present experimental and computational results show that for efficient "cutting" the following conditions for the two atomic sites to be separated by the knife should be satisfied. First, the sites should be located far from each other and connected by a chain of saturated bonds so that intersite electron migration can be reduced. Second, the chemical environments of the atomic sites should be as different as possible.
