DESCRIPTION:Speakers: Sergey Yurchenko (University College London)\nThe ne
 xt generation of ground-based telescopes\, which complement the space miss
 ions\, are aimed at HR (R ~ 100\,000) studies. Ground-based high resolutio
 n Doppler spectroscopy (HRS)\,  pioneered by Snellen\, has been used to ch
 aracterise the atmospheres of a growing number of exoplanets in recent yea
 rs. None of this is possible without the necessary laboratory data. While 
 spectroscopic and other data needs for studies of Earth-clone exoplanets a
 re well met by databases constructed for studying our own atmosphere\, suc
 h as HITRAN\, this is not the case for those exoplanets which will be the 
 first exoplanets to be characterised. These planets are hot and most are s
 ubject to strong bombardment by starlight (and presumably stellar winds). 
 Such studies require data  on hot molecules which are not generally availa
 ble and which are in many cases not easily amenable to laboratory experime
 nts. In particular\, current developments in exoplanetary observations are
  fueling the requirement for HR data. This creates new challenges for labo
 ratory spectroscopy projects like ExoMol\, which have been mainly concerne
 d with completeness (important for low resolution-based retrievals) rather
  than HR studies. The field of the HRS of exoplanets is growing extremely 
 fast and urgently demanding high precision molecular data. Failures to det
 ect molecules in atmospheres of exoplanets can often be attributed to the 
 lack of the underlying quality of the line positions. \n\nThe [ExoMol data
 base][1] contains extensive line lists for approximately 80 molecules\, in
  most cases for several isotopically substituted variants ("isotopologues"
 )\, with over 700 billion molecular transitions and two formal releases. T
 he current ExoMol activity aims at providing high accuracy  spectroscopic 
 data for high resolution studies of exoplanetary atmospheres. Novel theore
 tical techniques are being used to provide similar high accuracy line list
 s for isotopically substituted species and to generate pressure broadening
  data.\n\n\n  [1]: http://exomol.com\n\nhttps://iaus379.aip.de/event/16/co
