We examine the radiative {omega}{yields}{pi}{sup 0}{eta}{gamma} and {rho}{yields}{pi}{sup 0}{eta}{gamma} decays in a phenomenological framework. We consider the vector meson dominance mechanism, chiral loops, intermediate a{sub 0}-meson and {rho}-{omega} mixing. We find the values of the decay width coming from the different amplitudes and compare the results with other studies. We observe that the a{sub 0}-meson intermediate state is very important in the case of the {rho}{yields}{pi}{sup 0}{eta}{gamma} decay and small in the other case for which vector meson dominance contribution is dominant.
