本文分析了4-正戊基-d11-4′-氰基联苯（5CB-d11）、4-正戊基-d11- 2，3，5，6-d4-4′-氰基联苯（5CB-d15）和4-正戊基-2，2 ′，3，3 ′，5，5 ′，6，6 ′-d8-4′-氰基联苯（5CB-d8）在100 ℃范围内的氘谱，得到了偶极和四极分裂。质子-{氘}双共振实验5CB-d15已被分析，得到质子间偶极耦合，再次在温度范围内的100 ℃。这些数据已被用来确定分子中的刚性子群的有序矩阵的元素。
The deuterium spectra of 4-n-pentyl-d11-4′-cyanobiphenyl, (5CB-d11), 4-n-pentyl-d11-2,3,5,6-d4-4′-cyanobiphenyl, (5CB-d15) and 4-n-pentyl-2,2′,3,3′,5,5′,6,6′-d8-4′-cyanobiphenyl (5CB-d8), measured at temperatures within the nematic range, have been analysed to yield both dipolar and quadrupolar splittings. Proton-{deuterium} double resonance experiments on 5CB-d15 have been analysed to give inter-proton dipolar couplings, again at temperatures within the nematic range. These data have been used to determine the elements of the ordering matrices for most of the rigid sub-groups in the molecule.
