Abstract

Some recent work on doubly charged molecular ions is described. The method of ion photofragment spectroscopy has been applied to the N₂²⁺ and NO²⁺ dications. The (8,2) band of the A ¹$PI_u - (Chi) ¹(Sigma) _g⁺ transition was recorded at high spectral resolution. Line positions and linewidths were measured. It was found that levels of f-symmetry of the A state were more strongly predissociated than levels of e-symmetry. Attempts to observe structured photodissociation of NO²⁺, despite aid from large scale ab initio calculations, failed.
