Abstract:Photodissociation dynamics of water involving its B electronic states yielding OH(A2Σ+/X2Π)+H(2S)products has been intensively investi-gated by both experimental and theoretical studies[1].Theoretically,the Dobbyn-Knowles potential energy surfaces(DK PESs)[2]based on limited complete active space self-consistent field(CASSCF)points were used in dynamic studies for water photodissociation and O+H2 reaction about 20 years ago,but the accuracy is not enough to meet current re-quirements.
