Departures from axisymmetric morphology and dynamics in spiral galaxies

New H I synthesis data have been obtained for six face-on galaxies with the Very Large Array. These data and reanalyses of three additional data sets make up a sample of nine face-on galaxies analyzed for deviations from axis ymmetry in morphology and dynamics. This sample represents a subsample of g alaxies already analyzed for morphological symmetry properties in the R ban d. Four quantitative measures of dynamical nonaxisymmetry are compared with one another and to the quantitative measures of morphological asymmetry in H I and the R band to investigate the relationships between nonaxisymmetri c morphology and dynamics. We find no significant relationship between asym metric morphology and most of the dynamical measures in our sample. A possi ble relationship is found, however, between morphology and dynamical positi on angle differences between approaching and receding sides of the galaxy.
