摘要：

The orientational order of 4-n-hexyloxybenzilidene-4'-fluoroaniline, (FAB-OC6) and its 4-n-heptyloxy analogue, (FAB-OC7), studied by means of H-2 NMR and F-19 NMR is reported. The entire temperature range of the liquid-crystalline phases (S(B), S(A) and N for FAB-OC6, S(B) and S(A) for FAB-OC7) have been investigated. The results are discussed in relation to previous X-ray diffraction measurements. The chemical shift tensor components of the fluorine bond, evaluated from the F-19 NMR spectra are compared with previous results.
