The study we present is based on IRAM 30-m CO(1-0) observations of 11 galaxies with a close companion selected from the Sloan Digital Sky Survey (SDSS). The pairs have mass ratios $\\leq$4, projected separations r$_{\\mathrm{p}} \\leq$30 kpc and velocity separations $\\Delta$V$\\leq$300 km s$^{-1}$, and have been selected to exhibit enhanced specific star formation rates (sSFR).
