Abstract

The 110−101 transition of H2 18O, has been searched for in several sources without positive detection. However, in NGC 2264 and NGC 7538, possible emission features are suspected. Implications of these features, if confirmed, are discussed. Our best upper limit obtained in Orion (0.9 K) indicates that in that cloud, the water abundance should not be more than 1% that of CO.
