The supernova remnant IC 443 provides a striking example of a shock wave impacting a molecular cloud, producing intense emission along several narrow boundaries or "ridges." Observational evidence suggests that these molecular shocks are either partially dissociating with the degree of dissociation varying from point to point or that there are multiple shocks, possibly a mixture of low-velocity, nondissociating C-shocks and higher-velocity, dissociating J- shocks. We propose observations of the SI(25), SiII(35), FeI(24), FeII(26,35), OI(63,145), and CII(158) FIR fine-structure lines and the high-J CO lines at selected positions throughout the remnant. These observations will coincide spatially with existing observations of H2, high-velocity HI, low-J CO, H2CO, HCO+, HCN, CS, H51alpha, and OH and will serve as excellent discriminators of the various shock models which have been proposed.
