Interstellar molecules: guides for new chemistry
, 2010 Interstellar space is among the most remarkable chemical laboratories in the universe. The existence of many unstable species with low-valent main group elements in the interstellar medium inspired us to investigate the feasibility of laboratory ...

Photodissociation of interstellar N2 [PDF]
, 2013 Context. Molecular nitrogen is one of the key species in the chemistry of interstellar clouds and protoplanetary disks, but its photodissociation under interstellar conditions has never been properly studied. The partitioning of nitrogen between N and

Synthesis of Molecules in Interstellar Clouds & Star Formation [PDF]
, 1981 237-240Study of the formation and destruction processes of interstellar molecules may throw certain light on interstellar medium. Formation and destruction processes of some interstellar molecules are proposed on the basis of laboratory data.

The formation of molecular hydrogen in the interstellar medium
, 2010 H2 is the most abundant molecule in the interstellar medium and forms on the surface of interstellar dust grains. Laboratory studies have been conducted of HD formation on a dust grain analogue, which is a highly-oriented pyrolytic graphite surface ...

Computational Study of the Reactions of Interstellar Molecules: CH2 Reacting with HCNO and HNCO
, 2023 Association reactions among small molecules known to exist in the interstellar medium are interesting for theories on the origins of life. A screening of thousands of reactions, using machine learning estimates of energy barriers, identified the reaction

The Infrared Complex Refractive Index and Band Strengths of Coronene Thin Films
The Astrophysical JournalPolycyclic aromatic hydrocarbon (PAH) molecules have long been theorized to be present in a multitude of interstellar environments. The radio-frequency detections of specific cyanosubstituted PAH molecules in the Taurus Molecular Cloud have provided new ...

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 ...

Considerations Regarding Cometary and Interstellar Molecules. [PDF]
The Astrophysical Journal, 1942 The visual continua in the spectra of three nebulae photographed with a narrow slit are not produced by the blending of atomic emission lines but must have a physical origin. Several strong He I emission lines just beyond the Balmer limit may tend to vitiate measurements of the intensity distribution in the Balmer continuum on plates taken with a wide ...
