Intermolecular Coulombic decay (ICD) is a process whereby a photoexcited molecule relaxes while ionizing a neighbouring molecule. ICD is efficient when intermolecular interactions are active and consequently it is usually observed in weakly bound systems. Now, an efficient ICD is shown to occur even between unbound pyridine molecules excited at ambient-light intensities.
