Vibrational state-selected photodissociation of ClO+ Academic Article

abstract

• We report on the UV photodissociation of specific vibrational states (v = 2-45) of ClO + using velocity map ion imaging. The high vibrational states of ClO + are prepared via a double resonant scheme through the ClO (A 2) state and ion-pair states followed by photoionization with a third photon. The absorption of a fourth photon results in photodissociation of the ClO + into two dominant asymptotic channels. The Cl + and O + fragment ion images reveal information on both the energetics of high-lying cation vibrational states and the low-lying dissociative electronic states that correlate to Cl +( 3P) + O( 3P) and Cl( 2P) + O +( 4S) asymptotic channels. We also report ab initio potentials for the bound ClO + and ion-pair states as well as calculations of the ClO + excited states relevant to the photodissociation process. 2012 Elsevier B.V.
