Photodissociation of nitrous oxide near 203 nm has been studied by a combination of high resolution slice ion imaging technique and (2+1) resonance-enhanced multiphoton ionization (REMPI) spectroscopy of N_2(X~1∑_g~+) via the (a"~1∑_g~+) state. We have measured the recoil velocity and angular distributions of N_2 fragments by ion images of the state-resolved photofragments. The N_2 fragments were highly rotationally excited and the NN-O bond dissociation energy was determined to be 3.635 eV. Also, we investigated the photofragment images from the photodissociation of N_2O clusters with various stagnation pressures.
