Flow was created in freely suspended liquid crystal films in the smectic C phase using gradients in the surface tension to drive the motion. The director field was distorted into a pattern of vortices which wind upon themselves while the gradient was being applied. The dependence of the pattern in the director field for topological defects of index S = +1,0, or $-$1 are reported. The flow pattern for the S = $-$1 defect has not been observed in other flow fields. The diffusion constant for the c-director orientation is extracted from the orientation field patterns under flow and are compared to other independent measurements. / Source: Dissertation Abstracts International, Volume: 57-02, Section: B, page: 1172. / Major Professor: David van Winkle. / Thesis (Ph.D.)--The Florida State University, 1995.
