Searches for interstellar imidazole and cyanoform.
Abstract
The reported observations were made in March 1979 with the 20 m millimeter-wave telescope of the Onsala Space Observatory. Observations were performed by position switching in the total power mode, azimuth offsets typically being one degree. The sources observed include dark and molecular clouds, and the carbon star IRC+10216. The observational data are presented in a table. No lines were detected to the indicated limits regarding the peak-to-peak antenna temperature. The negative results regarding the observed cyanoform band provide limits on peak-to-peak antenna temperature also for HCOOH.
