Chemistry in the Interstellar Medium
Annual Review of Physical Chemistry, 1995Over the past 25 years, astronomers have discovered a large number of gas-phase molecules in space, ranging in size up to more than 10 atoms. The molecules, which are mainly organic in nature and comprise both normal and abnormal species, are located between stars, in regions known as interstellar clouds, which contain both gaseous material and ...

The chemistry of the interstellar medium
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1988Abstract There has been a dramatic advance in our appreciation of the richness of the molecular component of the interstellar medium, mainly brought about by combining laboratory spectroscopic measurements with radioastronomy search programmes.

Interstellar Organic Chemistry
Nature, 1972Most of the interstellar organic molecules have been found in the large radio source Sagittarius B2 toward the galactic center, and in such regions as W51 and the IR source in the Orion nebula. Questions of the reliability of molecular identifications are discussed together with aspects of organic synthesis in condensing clouds, degradational origin ...

Interstellar Anions: The Role of Quantum Chemistry
The Journal of Physical Chemistry A, 2015Six anions have been conclusively detected in the interstellar medium (ISM). They all arrived within a five-year window ending five years ago. Why have no new anions been detected? It is likely a lack of laboratory data for novel anions. This work reviews the role that valence and dipole-bound excited states may play in the formation, detection, and ...

Multiply-charged ions and interstellar chemistry
Physical Chemistry Chemical Physics, 2011Gaseous molecules and ions, and even dust grains, can accumulate charge in the interstellar medium (ISM) by harvesting the energy of UV photons, cosmic rays, helium ions and metastable atoms. This Perspective views the various modes of gas-phase formation of multiply-charged cations and the possible impact of their reactions on the chemical and ...
