State and energy characterisation of fluorine atoms in the A band photodissociation of F2

The fluorine photodissociation dynamics in the first absorption band was completely characterised by detection of atomic . fluorine using resonantly enhanced multi-photon ionisation REMPI . Jet-cooled parent molecules were excited into the repulsive A 1 P state by a 3s ⁄ 1p electronic transition at 234 nm. Different intermediate excited states of atomic uu g y1 . 1
