  In order to investigate dynamical properties of spiral galaxies in the
Hickson compact groups (HCGs), we present rotation curves of 30 galaxies in 20
HCGs. We found as follows. 1) There is not significant relation between
dynamical peculiarity and morphological peculiarity in HCG spirals. 2) There is
no significant relation between the dynamical properties and the frequency
distribution of nuclear activities in HCG spirals. 3) There are no significant
correlations between the dynamical properties of HCG spirals and any group
properties (i.e., the size, the velocity dispersion, the galaxy number density,
and the crossing time). 4) Asymmetric and peculiar rotation curves are more
frequently seen in the HCG spirals than in field spirals and in cluster ones.
However, this tendency is more obviously seen in late-type HCG spirals. These
results suggest that the dynamical properties of HCG spirals do not strongly
correlate with the morphology, the nuclear activity, and the group properties.
Our results also suggest that more frequent galaxy collisions occur in the HCGs
than in the field and in the clusters.
