This volume gives and excellent survey of our present
knowledge of molecularprocesses in stellar and
proto-stellar objects. It reviews molecular physicsin
stellar environments and is intended to bridge the gap
between astrophysicists and chemists. The topics range from
the theoretical to the computational and include
observational data. Among the topics treated are questions
of stellar evolution, the determination of physical
propertiesand structures, and the chemical composition of
stellar protospheres. Opacity is studied in the context of
various types of stellar and proto-stellar objects.
