ExoMol: molecular line lists for exoplanet and other atmospheres
The discovery of extrasolar planets is one of the major scientific advances of the last two decades. Hundreds of planets have now been detected and astronomers are beginning to characterize their composition and physical characteristics. To do this requires a huge quantity of spectroscopic data most of which are not available from laboratory studies. The ExoMol project will offer a comprehensiv...
متن کاملExoMol line lists – III. An improved hot rotation-vibration line list for HCN and HNC
A revised rotation-vibration line list for the combined hydrogen cyanide (HCN)/hydrogen isocyanide (HNC) system is presented. The line list uses ab initio transition intensities calculated previously and extensive data sets of recently measured experimental energy levels. The resulting line list has significantly more accurate wavelengths than previous ones for these systems. An improved value ...
متن کاملExoMol molecular line lists XIX : high - accuracy computed hot line lists for H 218 O and H 217
Hot line lists for two isotopologues of water, H2O and H2O, are presented. The calculations employ newly constructed potential energy surfaces (PES), which take advantage of a novel method for using the large set of experimental energy levels for H2O to give high-quality predictions for H2O and H2O. This procedure greatly extends the energy range for which a PES can be accurately determined, al...
متن کاملExoMol line lists – XVIII. The high-temperature spectrum of VO
An accurate line list, VOMYT, of spectroscopic transitions is presented for hot VO. The 13 lowest electronic states are considered. Curves and couplings are based on initial ab initio electronic structure calculations and then tuned using available experimental data. Dipole moment curves, used to obtain transition intensities, are computed using high levels of theory (e.g. MRCI/aug-cc-pVQZ usin...
متن کاملExoMol line lists – I . The rovibrational spectrum of BeH , MgH and CaH in the X 2 + state
Accurate line lists for three molecules, BeH, MgH and CaH, in their ground electronic states are presented. These line lists are suitable for temperatures relevant to exoplanetary atmospheres and cool stars (up to 2000 K). A combination of empirical and ab initio methods is used. The rovibrational energy levels of BeH, MgH and CaH are computed using the programs LEVEL and DPOTFIT in conjunction...
