It is pointed out that in the decays [Formula: see text] the possible "molecular" component of the X(3872) should give rise essentially only to a [Formula: see text] final state with a predictable spectrum, and should yield virtually no contribution to decays into D + D - γ. The latter final state with charged D mesons should however arise from the radiative decays of the short-distance core of the X(3872) through the transition X(3872) → ψ(3770)γ. Thus an observation of the radiative decays of X(3872) to pairs of neutral and charged D mesons would provide an insight into the internal dynamics of the X(3872) resonance.
