Abstract | The temperature dependences of the proton nuclear magnetic resonance (NMR) spectra of the solutes 1,3,5-trichlorobenzene, metadichlorobenzene, orthodichlorobenzene, 1,3-bromochlorobenzene, benzene and 2-butyne have been studied in the special ’zero electric field gradient’ mixtures 55wt% 1132-N-(4-ethoxybenzylidene)-4’-n-butylaniline (EBBA) and 70wt% (4-n-pentyl)-4’-cyanobiphenyl-EBBA. The order parameter matrices obtained for each solute from an analysis of the NMR spectra indicate that the solutes experience a similar anisotropic potential in both mixtures. |
