The interaction of galaxies with molecular gas has been studied. The main purpose of this study is to learn in what case the inflow of molecular matter will induce a great amount of accumulation of molecular matter in kpc-scale near the center of galaxies and how long this process lasts. It is found that if the fate of the interaction leads to the merger of both galaxies, the starburst activity might occur in both interacting galaxies, as in NGC 520.
