Using a counting scheme which treats the light pseudoscalar and the light vector-meson nonet on equal footing, the decays of the narrow light vector mesons into a pseudoscalar meson and a dilepton and of the η′ meson into an ɷ meson and a dielectron are calculated. Since all required parameters but one can be determined by other reactions, one has predictive power for the considered decay rates and form factors. The calculated partial decay widths are in good agreement with the available experimental data.
