dc.descriptionWe present the results of the stellar and ionized gas kinematics of 13 bright peculiar Virgo cluster galaxies. The stellar velocity field are mostly consistent with a rotation pattern, but some of them shows interesting features such as; S-shaped stellar isovelocity contours in NGC 4064, and signatures of kinematical distinct components in NGC 4429, and NGC 4698. This latter galaxy and NGC 4424 exhibit extremely low (V/sigma)* values suggesting that these galaxies are the result of mergers. The ionized gas velocity fields are more disturbed than the stellar velocity fields, displaying non-circular motions. Most galaxies in the sample reveals kinematical signatures that can be associated to gravitational interactions such as; mergers or tidal interactions, being specially clear in the "truncated/compact" galaxies. Moreover, most of the sample galaxies show evidence for both gravitational interactions, and ICM-ISM stripping. Thus the evolution of a significant fraction of cluster galaxies is likely strongly impacted by both effects.
