A majority of the luminous infrared galaxies (LIGs) are known to be interacting/merging galaxies. It has been suggested that the high IR luminosities of these galaxies are due to the starburst activities triggered by the interactions. Questions such as when and where starburst begin during an interaction, what are the physical conditions required for starburst to occur and how does the interaction proceed, remain unanswered. In order to address these questions, we have undertaken a project to study 15 LIGs at different stages of interaction as judged by the separation between the nuclei of the two galaxies and the morphology of the system as a whole. In this poster, we compare 20cm radio continuum observations from the Very Large Array (VLA) with CO observations made with the Berkeley-Illinois-Maryland Association millimeter interferometric array (BIMA) for selected galaxies in our sample.
