- 論文の詳細を見る
The binary mass diffusion constants of methyl red in p-butoxybenzylidene-n-octylaniline have been measured by forced Rayleigh scattering. Because of the different activation energies between the diffusion constants D_<//> and D_⊥ in the smectic A (S_A) and B (S_B) phases, the anisotropy D_<//> / D_⊥ drastically changes from 0.028 to 1.67 with the phase sequence through S_B, S_A and nematic (N). In S_B, D_<//> is much smaller than D_⊥, while D_<//> gets larger than D_⊥ in S_A near the phase transition temperature to N, T_<AN>. The anomalous behavior at T_<AN> is also discussed.
