摘要：

We report QNS investigations of the eighth member of the 4-n-pentylphenyl-4'-n-alkyloxythiobenzoate homologous series (C(n)H2n + 1 O-PHI-COS-PHI-C5H11, n = 8 and PHI denotes the benzene ring), knwon as 8S5BAR. QNS measurements have been performed for a fully protonated sample as well as for the one with deuteriated terminal alkyl and alkoxy groups, in the phases: isotropic, nematic, smectic A and smectic C. The results obtained indicate the important role of fast reorientation within the terminal chains, including conformational changes.
