Abstract
The deuteron quadrupole splitting of d 2-EBBA and the nuclear shielding of the 129Xe isotope of xenon gas dissolved in various binary mixtures of the nematic liquid crystals ZLI1132 and d 2-EBBA and in the mixture of S1114 (16.8 wt percent) and d 2-EBBA (83.2) were studied over the temperature range from 360 K to 280 K. The 129Xe shielding is found particularly sensitive to phase transitions, and consequently, the 129Xe NMR spectroscopy can be utilized in determining phase diagrams of liquid crystals. In the cases studied, I ‒ N, N ‒ SA (induced) and SA (induced) ‒ SB (induced) phase transitions have been detected, and the phase diagram of the ZLI1132/d 2-EBBA system is reported.
