So in these experiments, the Zeolite represents a proof of concept, used because it was readily available for laboratory work to disseminate the observational data – it can be shown from the literature that the when adsorbed at the surface of cation-doped amorphous silicates, CO stretching vibrations occur at identical frequencies to those in Zeolites.
So far, studies have concentrated on the chemistry and physics occurring on-top of, in the bulk of, and involving the icy mantles of interstellar dust grains.

  Astrochemistry - Wikipedia, the free encyclopedia
Astrochemistry is the study of the chemicals found in outer space, usually in molecular gas clouds, and their formation, interaction and destruction.
As such, it represents an overlap of the disciplines of astronomy and chemistry.
Astrochemistry overlaps strongly with astrophysics in characterizing the nuclear reactions which occur in stars, the consequences for stellar evolution, as well as stellar 'generations'.

 Report of the Galactic Molecular Clouds and Astrochemistry Working Group
The major question in Astrochemistry and Molecular Clouds is how molecules and dust grains cycle from the circumstellar envelopes of dying stars through diffuse and dense interstellar clouds, and how they are affected by the formation of new stars.
The set-up is different from the 1990 report, where the Astrochemistry was largely organized by type of reaction, rather than type of astrophysical object.
The Clouds provide unique laboratories for investigating how astrochemistry and molecular cloud structures respond to different conditions of element abundances, stellar populations, external radiation field, mean pressure of the ISM, ambient large-scale gravitational potential, etc., in comparison with the quite different conditions in the Milky Way.

 Pacifichem 2005 Astrochemistry
The formation of molecules in extraterrestrial environments has fascinated scientists since the pioneering detection, of CH and CN in interstellar space.
This symposium focuses on the interdisciplinary field of astrochemistry, bringing together speakers from the fields of laboratory astrochemistry (dynamics, kinetics, and spectroscopy), astrochemical modeling (physicists), theoretical astrochemistry (computational chemists), and observational astrochemistry (astronomers).
By focusing on the interplay between observational data, kinetic modeling, and fundamental investigations of the details of specific molecular processes, we seek also to evaluate the emerging generalized concepts on the formation of astrochemically important molecules on the molecular level.

One major aim of this workshop was to encourage this interdisciplinary approach, and we successfully introduced many established researchers from outside the field to astrochemistry.
The astronomers were also introduced to the current state-of-the art in laboratory and theoretical chemistry research on surfaces, and were given an appreciation of the limitations of current laboratory / computer technology, when applied to many of the astronomical data needs.
Both laboratory experiments and theoretical chemistry were highlighted as key routes to understanding the astrochemistry that underpins the chemical evolution of star forming regions.
