Abstract
Weakly bound molecular complexes have been studied in the laboratory for more than 40 years. Interest in them was heightened when they were predicted to be important species in the chemistry of the atmosphere and the interstellar medium (ISM) and also because of their unusual rotational dynamics, described in some cases by nearly free rotation of monomers within the complex. About 15 years ago the interest was heated by the observation of microscopic superfluidity in small helium clusters. On the other hand, a number of unsuccessful tries to detect weakly bound complexes in the ISM considerably lowered the interest in their further investigations for astrophysicists. With this short review I would like to show a perspective for future studies of astrophysically relevant weakly bound molecular complexes in the laboratory and for their potential search in the ISM.
期刊介绍：
Molecular Astrophysics is a peer-reviewed journal containing full research articles, selected review articles, and thematic issues. Molecular Astrophysics is a new journal where researchers working in planetary and exoplanetary science, astrochemistry, astrobiology, spectroscopy, physical chemistry and chemical physics can meet and exchange their ideas. Understanding the origin and evolution of interstellar and circumstellar molecules is key to understanding the Universe around us and our place in it and has become a fundamental goal of modern astrophysics. Molecular Astrophysics aims to provide a platform for scientists studying the chemical processes that form and dissociate molecules, and control chemical abundances in the universe, particularly in Solar System objects including planets, moons, and comets, in the atmospheres of exoplanets, as well as in regions of star and planet formation in the interstellar medium of galaxies. Observational studies of the molecular universe are driven by a range of new space missions and large-scale scale observatories opening up. With the Spitzer Space Telescope, the Herschel Space Observatory, the Atacama Large Millimeter/submillimeter Array (ALMA), NASA''s Kepler mission, the Rosetta mission, and more major future facilities such as NASA''s James Webb Space Telescope and various missions to Mars, the journal taps into the expected new insights and the need to bring the various communities together on one platform. The journal aims to cover observational, laboratory as well as computational results in the galactic, extragalactic and intergalactic areas of our universe.
