Only the diamagnetic susceptibility and the second moment of the nuclear magnetic resonance show additive molar properties. 

Nuclear magnetic resonance spectroscopy gives precise information on complexation in solution. Equilibrium is rapidly established on an NMR time scale, hence only an average spectrum is observed and it is difficult to determine the spectrum of a pure complex. When complexation of a sugar or polyol with a diamagnetic ion occurs, all of the signals shift downfield. Equation (11.1) allows the variation of the shielding constant Ao- of the proton to be calculated when the nucleus is subjected to an electric field E whose projection on the C-H bond is... 

The diamagnetic, monomeric thorium derivative has been completely characterized by its 1h and 13C nuclear magnetic resonance spectra. Data are shown in Table II. In particular the NMR spectrum, proton-coupled, shows a triplet pattern clearly due to splitting by two equivalent hydrogen atoms. The uranium metallocycle is paramagnetic (yg = 2.7 B.M.) and we have only observed its NMR spectrum. A titanium metallocycle,... 

In solutions, nuclear magnetic resonance is of use from the H paramagnetic shift (AAv) of a reference compound, corrected for the diamagnetic contribution of the ligands, the paramagnetic susceptibility is evaluable using the Evans method [10]...
