Combining Fourier transform nuclear quadrupole resonance (FT-NQR) spectroscopy and mass spectrometry (MS) to study the electronic structure of titanocene dichlorides
Original language description
A combination of nuclear quadrupole resonance spectroscopy (NQR) and mass spectrometry (MS) has been used to observe trends in electronic structure in three titanocenes: bis(cyclopentadienyl) titanium dichloride (eta(5)-C5H5)(2)TiCl2, bis(pentamethylcyclopentadienyl) titanium dichloride (eta(5)-C-5(CH3)(5))(2)TiCl2 and dimethylsilylene-bridged ansa bis(cyclopentadienyl) titanium dichloride Si(CH3)(2)(eta(5)-C5H5)(2)TiCl2. Using MS, electron ionisation mass spectra of these compounds are presented withinthe context of the entire homologous series with one to five methyl groups on each cyclopentadienyl ligand. A dedicated NQR spectrometer was constructed for this study with a sensitivity sufficient to precisely determine the NQR resonant frequency of Cl-35 atoms using 3 g samples of these titanocenes. The observed frequencies are thus 11.784, 11.930 and 10.863 MHz at 298 K. The results demonstrate that NQR using a relatively simple apparatus can be used as a sensitive and cost effective
