摘要：

We have conducted extensive astronomical searches for the N-bearing ring molecules pyridine, quinoline and isoquinoline towards the circurnstellar envelopes of carbon-rich stars, and for interstellar pyrimidine in hot molecular cores. Here we report the derived upper limits oil the column densities of these molecules, and summarize the current status of these observations. (c) 2005 Published by Elsevier Ltd oil behalf of COSPAR.
