Perfluorocarbons are a special family of molecules, which rarely exist in nature due to the high energy required to build the carbon-fluorine bond. The strong electronegative effect of fluorine on neighboring atoms is still awaiting a clear electronic structure picture description. The insight to be gained is proposed to be the origin of the unique functionalities of these systems. We have used soft X-ray XAS/XES/RIXS to draw a full electronic picture of the unoccupied and occupied molecular orbitals in solution. The effect of fluorine was observed and fingerprinted on Perfluorodecalin as a model system. The obtained experimental spectra are explained with ab initio calculations using ORCA.
