N2 - Visible photodissociation of (NO)2+ at 532–692 nm was investigated by ion imaging experiments and theoretical calculations. From images of photofragment NO+, we obtained the translational energy, which increased with excitation energy. Anisotropy parameter increased from β = 0.7 at 692 nm to 1.4 at 532 nm. These results qualitatively agreed with theoretical calculations, in which (NO)2+ was predicted to be directly dissociated after the C∼←X∼ transition. However, a simple description with an impulsive dissociation model cannot reproduce photon energy dependence of the photofragment energy and angular distributions, implying the importance of multidimensional analyses of potential energy surfaces.
