T he basic form of the database is extensive line lists; these are supplemen ted with partition functions, state lifetimes, cooling functions, Land&eac ute; g-factors, temperature-dependent cross sections, opacities, k-coeffic ients and pressure broadening parameters. Currently containing 80 molecule s and 190 isotopologues totaling over 700 billion transitions, the databas e covers infrared, visible and UV wavelengths. The field of the HR spectro scopy of exoplanets is growing extremely fast and urgently demands molecul ar data of high precision. Failure to detect molecules in atmospheres of e xoplanets is often attributed to the lack of the underlying quality ofthe line positions.  These developments have led us to begin a systematic attempt to improve the accuracy of the line positions for the line lists contained in the database. Our new ExoMolHD project aims to provide compre hensive line lists to facilitate their use in characterization of exoplane ts using high resolution Doppler shift spectroscopy. Progress on this obje ctive will be presented. END:VEVENT END:VCALENDAR
