Abstract: We performed 12CO(J = 1–0) mapping observations toward four interacting galaxies in early and mid stages of the interaction using the 45-m telescope. Comparing to isolated galaxies whose data were also obtained with the 45-m, we found that interacting galaxies have (1) lower degree of the central concentration of molecular gas, (2) high molecular gas fraction (the mass of molecular gas to the sum of the mass of molecular gas and atomic gas ratio) and (3) no difference in Kennicutt-Schmidt law.
