The coupling constants of {alpha}0 {yields} {omega}{gamma}, f0 {yields} {omega}{gamma}, {alpha}0 {yields} {rho}{gamma}, and f0 {yields} {rho}{gamma} are calculated using 3-point QCD sum rules. We estimate the coupling constants g{alpha}0{omega}{gamma}, gf0{omega}{gamma}, g{alpha}0{rho}{gamma} and gf0{rho}{gamma} which are an essential ingredient in the analysis of physical processes involving isoscalar f0(980) and isovector {alpha}0(980) mesons.
