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

High-resolution 13C 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-d17). The spin-lattice relaxation times (T1) for each carbon atom in the molecules were measured to elucidate the differences between molecular interactions in CBOOA and CBOOA-d17.
