Abstract
A large number of different molecular species have been found in the gas/dust envelopes that surround asymptotic giant branch stars. The relative simplicity of their geometry and kinematics, and the large variety in their physical and chemical (C/O<1 as well as >1) characteristics, make them excellent targets for the study of molecular formation processes. This review presents a compilation of estimated molecular abundances, discusses the uncertainties involved in their estimate, and makes some comparisons with theoretical predictions.
