Orientational autocorrelation function
WitrynaDynamical behavior of a nematic liquid crystal in a silica aerogel host near the nematic-isotropic phase transition was studied by quasielastic light scattering. Just below the nematic-isotropic phase transition temperature two modes were observed. The faster mode does not depend on the scattering vector and is attributed to the intrapore … WitrynaTime Correlation Functions Correlations between two di erent quantities A and B are measured using a time correlation function : C AB (t) = < A(t) · B (0) > Such time correlation functions are interesting since : They give a picture of the dynamics in the system Their time integrals are often related to various transport properties
