ACS ASTROCHEMISTRY SUBDIVISION

Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description: Description:

 

The Subdivision of Astrochemistry of the ACS Division of Physical Chemistry provides an interdisciplinary "home" for individuals interested in astrochemically related research via experiments, theory, observations, and modeling. In addition, the Subdivision contributes to the programs of the Division of Physical Chemistry in areas of special interest to Astrochemists. We hope that this web site will be a resource for Subdivision members and for those generally interested in the astrochemical aspects of chemistry.  Please let us know how we can make this site more useful to you by directing your comments and suggestions for future officers as well as for forthcoming astrochemistry symposia to the Chair, Chair-Elect, Vice Chair, or secretary.

Astrochemistry is the study of the abundances and chemical reactions of atoms, molecules, and ions and how they interact with radiation in the gas phase and in the condensed phase in Solar Systems and in the Interstellar Medium (ISM) leading to the formation and breaking of chemical bonds. This results in the formation of new molecules ranging from simple diatomics such as molecular hydrogen to complex, astrobiologically important organic molecules. Astrochemistry presents both an interdisciplinary and a multidisciplinary field with ties to the traditional disciplines chemistry, planetary science, chemical biology, physics, and astronomy. Here, chemistry, defined as the change of matter is vital in unraveling the chemical and astrobiological evolution of matter on the microscopic (elementary chemical reactions) and also on the macroscopic level (planets, moons, interstellar medium).

 

 

 

Since the present composition of each macroscopic environment reflects the matter from which it was formed and the chemical processes which have changed the chemical nature since the origin, a detailed investigation of the processes altering the chemical composition of the pristine environment is critical to rationalize its contemporary makeup and to understand its origin and chemistry. Astrochemistry exploits molecular tracers to rationalize the origin and chemical evolution of the Interstellar Medium and of Solar Systems by combining laboratory studies (chemical dynamics and kinetics, spectroscopy), theoretical chemistry, astrochemical modeling, astronomical observations, and space missions. This work requires a concerted interdisciplinary relationship between chemists, physicists, astronomers, chemical biologists, and planetary scientists.
