High field high resolution NMR has been used to determine the components of the magnetic susceptibility tensor and the angular correlation factors g 2 for nitrobenzene, toluene, and benzene. For nitrobenzene an accurate concentration dependence study of the effective susceptibility anisotropy and asymmetry has been made. The angular correlation around the three principal molecular axes has been studied. For all compounds the g2 factor along the main molecular axis is in agreement with that found by the Cotton-Mouton effect and depolarized Rayleigh scattering studies. For nitrobenzene and toluene g2 cannot be interpreted in terms of simple monomer-dimer equilibria. For benzene a dimer model is shown to describe the liquid behavior satisfactorily.
