Intermolecular Coulombic Decay Knows No Bounds

2022-10-12 Prof. G. Aravind, Indian Institute of Technology Madras

ABSTRACT :

Electronically excited molecules in weakly bound systems could dispose of the excess energy by ionizing their neighbours. Since the excitation decays via Coulombic interactions between the excited molecules and their neighbours, it is called Intermolecular Coulombic Decay (ICD). Following its prediction in 1997 [1], numerous exciting experiments measured ICD in bound systems, such as Van der Waals and hydrogen bonded clusters [2]. In this talk, we will discuss such studies on ICD in bound systems and then explore the possibility of its operation in unbound systems as well [3]. References: [1] L. S. Cederbaum, J.
