Abstract
Extensive mass loss from red giants is the major source of processed material to the interstellar medium, and probably affects their evolution. Circumstellar envelopes, produced as a result of the mass loss, have come under increasing scrutiny by many authors, both observational and theoretical (Zuckerman, B. 1980, Ann. Rev. Astr. Ap., 18, 263). The study of circumstellar chemistry is important from several viewpoints, but is hampered by the lack of adequate data. The lack is particularly severe for oxygen-rich circumstellar envelopes (O-rich CSE’s), in which very few molecular species have been detected. We have, therefore, undertaken a program of systematically searching for molecular species diagnostic of the chemistry in these objects.
