Discusses the wide range of chemistry in astronomical environments with an emphasis on the description of molecular processes that critically influence the nature and evolution of astronomical objects and the identification of specific observations that directly address significant astronomical questions. The subject areas of the symposium included atomic and molecular processes at low and high temperatures and photon interactions, the chemical structure of molecular clouds in the Milky Way and in external galaxies, the chemistry of outflows and their interactions with the interstellar medium, the chemical connections between the interstellar medium, and the solar system and pregalactic chemistry.

`The book is bursting with ideas. ... The territory covered ... is immense. ... There is something here to interest most professional astronomers, and the large number of review papers ensures that the material is accessible to non-experts. ... The presentation of the proceedings is exemplary. ... The individual contributions ... have been carefully edited and integrated into a balanced and subtle account which shows all the virtues of the chemists' approach. ... The Editor has taken great pains over the indexing, and as a result the book is a delight to use. ... The book is self-recommending to those working in the field or in related areas, but I would also recommend it to astronomers and astrophysicists with more general interests, who cannot fail to be stimulated by it.'
The Observatory, 113:1115
`Without any doubt this book is a gold mine for scientists actively working in astrochemistry.'
