Fragmentation of tetravinylsilane and dimethylphenylsilane by electron impact was investigated by mass spectroscopy. Mass spectra was measured at 70eV and compared with NIST database. Some of the most abundant peaks were discussed and reaction mechanisms of ion decomposition were predicted. Furthermore, there are presented tables which are containing treshold energies of most abundant ions. Was discussed influence of molecule structure on ionisation properties. Measured were positive ions only.
