Scientific paper

Observations of several interstellar molecules toward the highly perturbed B and G clouds associated with SNR IC 443 are reported. The results suggest that hot and dense material is present in the SNR, and that shocks are present in both regions. The HCO(+) abundance is shown to be a few times greater that found in cold quiescent gas, in contradiction with previous results. The SO, CS, CN, and NH3 abundances are similar to those found in cold dark clouds.
