Photodissociation experiments of state-selected and oriented triatomics are presented. Selective ionization using REMPI in combination with two-dimensional ion-imaging allows us to measure both the internal energy and angular distribution of the fragments. The dissociation of N{sub 2}O is studied using one laser around 204 nm for both the dissociation of the molecule and the ionization of the fragments. The angular distributions of O({sup 1}D) and N{sub 2}(J) are presented and implications of these results on the dissociation dynamics are discussed. {copyright} {ital 1997 American Institute of Physics.}
