Partial dissociative emission cross sections and product state distributions of the resulting photofragments

This paper relates the partial cross section of a continuous optical emission into a given scattering channel of the lower electronic state to the photofragment population. This allows one to infer partial emission cross sections 'non-optically' from product state distributions; in computations, explicit construction of exact scattering states is therefore avoided. Applications to the emission spectra of NaI, CO₂, and pyrrole are given. It is also demonstrated that a similar relationship holds between partial cross sections of dissociative photoionization and distributions of ionic fragments over final product channels.
