Abstract The 27 Al NMR signal from trimethylaluminum (TMA) in solution is shifted to lower field with:(i) increasing temperature;(ii) decreasing concentration of TMA; and (iii), more markedly, the increasing solvating power of the solvent. This shift reflects an increase in the degree of dissociation of the dimer to the monomer. Thermodynamic data (K d, ΔH d, ΔS d) of the TMA dissociation have been calculated from the observed values of the NMR ...
