Over the possible role of metal atom clusters in cosmochemistry and in the origin of life
Revista de Química, 1992 We present here the hypothesis of a possible relationship between metal atom clusters and the formation of organic molecules in the interstellar medium and on small bodies as a possible pathway to the origin of such molecules.

Elastic Properties of Titan Tholins Revealed by Brillouin Spectroscopy
Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.Abstract Titan tholins, complex organic solids synthesized by simulating photochemical processes in Titan's atmosphere, are widely regarded as analogs to organic surface materials on the Saturnian moon. Their mechanical properties are critical for understanding the evolution of Titan's geomorphology and crustal layering.

Photoabsorption and photodissociation of molecules important in the interstellar medium [PDF]
, 1993 The photo absorption, photo dissociation, and fluorescence cross sections of interstellar molecules and radicals were measured in the vacuum ultraviolet region. These quantitative optical data are useful for understanding of the formation and destruction

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2445-2465, October 2026.Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Photochemistry of interstellar molecules [PDF]
, 1971 The photochemistry of two diatomic and eight polyatomic molecules is discussed quantitatively. For an interstellar molecule, the lifetime against photodecomposition depends upon the absorption cross section, the quantum yield or probability of ...

Molecular filming: A director's grammar for visualizing chemistry in motion
Bulletin of the Korean Chemical Society, Volume 47, Issue 9, Page 1042-1057, September 2026.Molecular filming names the practice, not just the product, of ultrafast structural science. In deliberate analogy to molecular editing, which rewrites connectivity in space, molecular filming records geometry in time, assembling time‐ordered structural frames into a movie of atomic motion and recasting the field as a grammar of directorial choices ...

Searches for interstellar molecules of potential prebiotic importance
, 2004 Interstellar chemistry leads to the formation of many prebiologically important molecules and is therefore of the fundamental interest to Astrobiology. Many organics can be produced in the gas phase where they can be detected.

Microwave Evidence For Interstellar Molecules [PDF]
Highlights of Astronomy, 1971 Some time ago, optical astronomy was successful in detecting the first molecular species in interstellar space. However, these have been limited to the three diatomic molecules CH, CH+, and CN. Consideration of this list made it rather natural, after the development of microwave astronomy, for some attention to be given to a search for OH, which has a ...
