We present a calculation of the coupling constant of f0→ργ and a0→ργ decays from the point of view of the light cone QCD sum rules. We estimate the coupling constants gf0ργ, which are an essential ingredient in the analysis of physical processes involving the isoscalar f0(980) and the isovector a0(980) mesons.
