DFG Research Unit 1789 „Intermolecular Coulombic Decay“

Intermolecular Coulombic Decay (ICD) is a mechanism, by which electronically excited states in atoms or molecules relax and transfer energy to their surroundings. In ICD, the excess energy which is present at one site is used to ionize an atom or molecule at another, e.g. neighbouring site. Although they are probably important in a lot of liquids, solvation systems and organic surfaces, ICD has only been known since approx. ten years. Best understood today is ICD in van-der-Waals clusters of rare gas atoms (see Fig.). The group at IOM uses electron-electron coincidence spectroscopy to investigate ICD in liquid jets and in free, neutral clusters.
