J. Jadzyn et al., DIELECTRIC-PROPERTIES OF MESOMORPHIC N-TPEBS IN ISOTROPIC-PHASE, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 48(8-9), 1993, pp. 871-874
Dielectric relaxation studies have been performed for the isotropic ph
ase ora series of mesogenic molecules of -alkyl-biphenyl]-2-[4-isothio
cyanatophenyl]ethane, CnH-2n+1-phi-phi-CH2CH2-phi-NCS (n-TPEB), for n=
7, 8 and 9. Two Debye-type dielectric absorption bands have been inter
preted as corresponding to the rotation around the short and long mole
cular axis.
