The results of a spectroscopic study of the pair of galaxies Tol 1238-364 and ESO 381-G009 are presented. Long-slit spectroscopy at different slit position angles combined with Laplace filtering of Hα images of the two galaxies allowed to isolate several circumnuclear and extranuclear regions. Physical properties have been derived by means of a grid of photoionization models computed with the code Cloudy 90. Star formation rates in both galaxies have been calculated and compared with their infrared emission, obtained from IRAS data after application of the Maximum Entropy method.

Abstract
The results of a spectroscopic study of the pair of galaxies Tol 1238-364 and ESO 381-G009 are presented. Long-slit spectroscopy at different slit position angles combined with Laplace filtering of Hα images of the two galaxies allowed to isolate several circumnuclear and extranuclear regions. Physical properties have been derived by means of a grid of photoionization models computed with the code Cloudy 90. Star formation rates in both galaxies have been calculated and compared with their infrared emission, obtained from IRAS data after application of the Maximum Entropy method.
