Abstract
The compounds η-cyclopentadienyl- and η-indenyl-(η-cyclo-octatetraene)titanium have been studied by e.s.r. spectroscopy at room and low temperatures. Titanium hyperfine and proton superhyperfine coupling parameters are accurately determined. Electronic-absorption spectra in the u.v.–visible and near-i.r. regions have also been recorded, and a coherent molecular-orbital diagram for both compounds is proposed. These results show that the proton hyperfine-interaction constant of the unpaired electron with the C8H8 ring is almost twice that with the other (five-membered) ring, and that the charge borne by the metal atom is close to unity.Keywords
