Abstract
The temperature dependences of the proton nuclear magnetic resonance ( NMR) spectra of the solutes 1,3,5-trichlorobenzene, metadichlorobenzen e, orthodichlorobenzene, 1,3-bromochlorobenzene, benzene and 2-butyne have been studied in the special 'zero electric field gradient' mixtur es 55wt% 1132-N-(4-ethoxybenzylidene)-4'-n-butylaniline (EBBA) and 70w t% (4-n-pentyl)-4'-cyanobiphenyl-EBBA. The order parameter matrices ob tained for each solute from an analysis of the NMR spectra indicate th at the solutes experience a similar anisotropic potential in both mixt ures.
