Abstract
The number of circumstellar molecules stands presently at 31. Seventeen of them consist of more than three atoms. This suggests the existence of considerable amounts of complex molecular species in the envelopes of red giants stars, especially the carbon-rich. In this review the observed molecular abundances in the by far most well studied source IRC+10216 are compared with theoretical calculations. The prospect for detecting more complex species and the search strategy are discussed.
