Short and Long-Range Correlations of N- (4′-n-pentyloxy benzylidene)-4-n-butylaniline (PBBA) Molecules in Smectic G and Glass of Smectic G Phases

Abstract The literature dielectric data of Johari and Goodby on the main relaxation in smectic G phase and on secondary relaxation in the glass of smectic G phase of PBBA has been analyzed to estimate and compare the local and long-range correlation parameters describing the molecular reorientations.
