Raman-spectroscopy of oligomeric SiO species isolated in solid methane

From the IR-spectra of matrix isolated SiO species a D2h-structure has been postulated for the dimer and a D3h-structure for the trimer. High quality Raman-spectra - necessary for the complete characterization - were missing so far. Here we report the Raman-spectra especially of the totally symmetric vibrations for Si2O2 and Si3O3 and their 16O/18O isotopomers isolated in solid methane. We also detect the most intense A1-vibration of Si4O4 and can assign it with its 16O/18O isotopic splitting. Ab initio calculations for all oligomers are presented in order to support the assignment of the spectra and to obtain geometric and energetic information about the oligomeric species which have been detected experimentally.
