Shocked CO is seen within the supernova remnant IC 443, in association with the accelerated H I and OH clouds. The CO lines have velocity widths of 20 km s/sup -1/ and appear to be optically thin. Co column densities in the shocked gas, approx.10/sup 16/ cm/sup -2/, are similar to those measured in the preshock cloud. The ratio of ground-state OH/CO column densities is enhanced by two orders of magnitude in one shocked region, as compared with preshock cloud.
