Gas-phase chemistry in the interstellar medium is driven by fast ion-molecule reactions. This, of course, demands a mechanism for ionization, and cosmic rays are the ideal candidate as they can operate throughout the majority of both diffuse and dense interstellar clouds.

Ever wondered if the chemical processes taking place in space could be related to the origins of life? The authors of this book, both experienced astrochemists, embark on a discussion to find the answers to this question and more, and include a general introduction to astrochemistry for chemistry students.

The answers to some of the most fundamental questions in science lie between the stars, in molecular clouds that serve as celestial laboratories. Disentangling the chemistries in extraterrestrial environments can provide clues about how planets form and shed light on problems in terrestrial chemistry that are difficult to investigate in the lab, and ...

Advances in Space Research, 1986
Astronomers have identified some 70 molecular species in dense interstellar clouds and the envelopes expelled by evolved stars. Some 75% of these are organic, including molecules with up to 13 atoms and with weights up to 147 daltons. Elements found in interstellar compounds include H, C, N, O, S, Si, and probably Cl.
