| Research Abstract |
The dynamic behaviour of twin dimer nematic liquid crystals were investigated for alpha,omega-bis(4-cyanobiphenyl-4'-yloxy)alkanes (BCBO-m, m = 7-10: the number of spacer methylene units) by dynamic light scattering and the frequencies of the splay, twist and bend modes were determined successfully. The frequencies of BCBO-m are dependent on m: they oscillate depending on the parity of m with exhibiting larger values for even-membered BCBO-m and decrease with increasing m. Such an odd-even oscillation in the splay and bend mode frequencies are governed by that in the elastic constants.
