An accidental resonance mediated predissociation pathway of water molecules excited to the electronic state†
Abstract
The predissociation dynamics of water molecules in the electronic state were studied using the time-resolved photoelectron imaging method. Both vibrationless and vibrationally excited states in the electronic state were studied, with an emphasis on the vibrational excitation effects on the predissociation dynamics of the state. Besides the well-known rotationally and non-rotationally mediated predissociation pathways (Proc. Natl. Acad. Sci. U. S. A., 2008, 105, 19148), an accidental resonance mediated predissociation pathway for the first bending mode excited state in the electronic state of H2O is revealed, providing an excellent example of competition between non-adiabatic decay pathways involving at least five electronic states.
