Production of O2 Herzberg states in the deep UV photodissociation of ozone.

ABSTRACT

High-resolution imaging experiments combined with new electronic structure and dynamics calculations strongly indicate that the O((3)P)+O(2) products with very low kinetic energy release (E(tr)<0.2 eV) formed in the deep UV (226 nm) photodissociation of ozone reflect excitation of the Herzberg states of O(2) A(')(3)Delta(u)(v=0,1,2) and A (3)Sigma(u)(+)(v=0,1). This interpretation contradicts the earlier assignment to very high (v> or =26) vibrational states of O(2)((3)Sigma(g)(-)).
