We analyze the line-of- sight velocities, velocity dispersion, emission line intensities and gas oxygen abundances for several tightly interacting systems (Arp 270, Arp194, NGC4631/56), including the star forming regions beyond the main bodies of galaxies. The long-slit observations were carried out at the 6-m telescope BTA. Conditions of star formation in the tidal debris are also shortly discussed.
