1 H and 19 F spectra of methoxypentafluorophenyltitanocene complexes have been analysed. They show the possibility of coupling between the methyl protons of the methoxy group and the two ortho fluorine atoms of the pentfluorophenyl ligand. Furthermore, anisochrony of the two ortho and the two meta fluorine atoms is detected in some cases. The analysis of conformational factors is presented.
