We present spectrophotometry of a sample of 26 Southern binary galaxies 17 pairs were confirmed to be physically associated with typical separation of tex2html_wrap_inline996. Pairs with velocity difference tex2html_wrap_inline998 are probably not physically bound. A comparison with field galaxies suggests that galaxies in pairs tend to have a younger population probably stimulated by tidal interaction. No correlation between the young population and projected separation was found.
