Interpretation of EI organometallics mass spectra applying isotopic patterns
Journal Title: CHEMIK nauka-technika-rynek - Year 2011, Vol 65, Issue 4
Abstract
This work presents results obtained from interpretation of EI mass spectra of organic derivatives of Pt, Mo, Ge, Sn and Pb multiisotopic metals, containing 4 10 stable isotopes. Use of computer- aided chemometric band composition analysis BCA applying isotope patterns enabled identification of all ions present in simple and complex bands of the spectra studied. For complex bands also ion contributions were determined. It was noticed that number of ions identified in mass spectra of compounds (ZPt, ZMo) with coordination complex p bonds between metal and carbon organic part Z exceeds distinctly that obtained for spectra of organometalics (ZGe, ZSn and ZPb) containing s covalent bonds.
