Abstract
The characteristics of the spiral structure of galaxies in compact groups (from the HCG and SDSSCGA catalogs) and in isolation (from the CIG catalog) have been obtained and analyzed. The dependence of the type of spiral pattern on the spatial environment of galaxies has been studied. The conclusions about how a tidal interaction affects the spiral structure have been drawn. The fraction of grand design spirals in compact groups is shown to be considerably higher than that in a sample of isolated objects. Grand design galaxies in the field, on average, have bluer and narrower spiral arms. This may probably due to the absence of a tidal interaction that has a strong effect on the structure of galaxies in a crowded environment.
