Abstract

Sulfur hexafluoride (SF6) is a very strong greenhouse gas of anthropogenic origin. Its relatively high molecular mass leads to a very dense molecular spectrum which is quite difficult to analyze. Our groups performed recently strong experimental and theoretical efforts in order to assign and model many cold and hot bands of SF6, allowing to strongly improve the modeling of its atmospheric absorptiona . We present here a synthesis of the latest available data and global analyses performed thanks to the formalism and programs developed in Dijon. In particular, new progress has been realized towards the modeling of hot bands in the strongly absorbing ν3 region around 948 cm−1 . The results have been used tu fully update the SHeCaSDa database (http://vamdc.icb.cnrs.fr/PHP/shecasda.php) which is also accessible from the VAMDC portal (http://portal.vamdc.org) and will be included in future HITRAN and GEISA updates.
