13C high-resolution NMR study of the effect of the deuterium isotope on liquid crystal CBOOA-d17

Abstract High-resolution 13 C NMR experiments were performed in isotropic liquid and liquid crystalline phases of 4-octyloxy- N -(4-cyanobenzylidene)aniline (CBOOA) and its chain-deuterated analogue (CBOOA- d 17 ). The spin-lattice relaxation times ( T 1 ) for each carbon atom in the molecules were measured to elucidate the differences between molecular interactions in CBOOA and CBOOA- d 17 .
