We make detailed comparison between the high resolution CO (J=2-l, 1-0) maps obtained with the OVRO Millimeter Array and the 2.12 µm H2(v=1-0) S(1) multi-channel images obtained using a Fabry-Perot system with the UKIRT Infrared Array Camera. Both datasets cover an interstellar shockfront region in the vicinity of the Galactic supernova remnant IC 443, and provide complementary information of the strongly shocked molecular gas on scales of 0.01 pc and a few km s−1. Combining our data with other atomic/molecular line probes, we find that a combination of bow-shock and cloud internal shock can best describe the interface between the supernova blast wave and pre-existing molecular clouds.
