Complex Organic Interstellar Molecules

Annual Review of Astronomy and Astrophysics, 2009
Of the over 150 different molecular species detected in the interstellar and circumstellar media, approximately 50 contain 6 or more atoms. These molecules, labeled complex by astronomers if not by chemists, all contain the element carbon and so can be called organic. In the interstellar medium, complex molecules are detected in the denser sources only.

Interstellar Molecules and Dense Clouds

Science, 1971
Current knowledge of the interstellar medium is discussed on the basis of recent published studies. The subjects considered include optical identification of interstellar molecules, radio molecular lines, interstellar clouds, isotopic abundances, formation and disappearance of interstellar molecules, and interstellar probing techniques.

Prebiotic Astrochemistry and the Formation of Molecules of Astrobiological Interest in Interstellar Clouds and Protostellar Disks.

Chemical Reviews, 2020
Despite the generally hostile nature of the environments involved, chemistry does occur in space. Molecules are seen in environments that span a wide range of physical and chemical conditions and that clearly were created by a multitude of chemical ...

Interstellar Molecules

Scientific American, 1973
During the past three years, molecules have been discovered in interstellar clouds with an abundance and chemical complexity totally unexpected by astrophysicists. Twenty-three molecules in a total of 34 isotopic combinations have now been identified through radio spectral line observations at more than 75 wavelengths from 2 millimeters to 36 ...

Interstellar Molecules

Journal of Molecular Evolution, 1974
The study of interstellar molecules broadly includes two areas of interest. One area uses the unique ability of molecules to act as probes of the physical conditions in the cold, dense, visually opaque component of the interstellar medium. The physical properties of this and other components of the interstellar medium are summarized.

Quantum Mechanical Investigations on the Formation of Complex Organic Molecules on Interstellar Ice Mantles. Review and Perspectives

ACS Earth and Space Chemistry, 2019
The interstellar medium (ISM) is rich in molecules, from simple diatomic to complex organic ones, some of which have a biotic potential.

Interstellar molecules

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1987
Some 70 different molecular species have so far been detected variously in diffuse interstellar clouds, dense interstellar clouds and circumstellar shells. Only simple (diatomic and triatomic) species exist in diffuse clouds because of the penetration of destructive ultraviolet radiations, whereas more complex (polyatomic) molecules survive in dense ...
