The determination of the state of the excited photofragments gives informations on couplings occurring at large internuclear distance. The H(1s) + H(n = 2) photodissociation of H2 is well explained with a transition probability between the B and B' continua occurring at r ≈ 15a0. The H(1s) + H(n = 3) photodissociation of H2 presents unsolved questions.
