Scientific paper
Limits on column densities and production rates are derived in light of negative results from a search for HCN, CS, and CH3OH millimeter-wave emissions, along with two unidentified lines observed in Comet Kohoutek (1973 XII), from Comet Bradfield (1979l) after perihelion passage. In the case of HCN, the production rate is found to be lower than that reported for Comet Kohoutek even upon scaling of measurements relative to the observed OH emission from each comet.
