We investigate the radiative decays of the X(3872) to γV(V=ρ0,ω) in the molecule scenario, where the X(3872) is regarded as a pure hadronic molecule of the DDˉ∗+c.c in an S-wave with the quantum numbers JPC=1++. The radiative processes were assumed to occur via the triangle hadronic loops, and the relevant calculations were conducted using an effective Lagrangian approach. It is found that the absolute decay widths are model-dependent, but the relative width ratio is rather independent of the model parameter. Moreover, the calculated results indicate that the radiative decays of the X(3872) are strongly influenced by the molecular configuration characterized by the proportion of the charged and neutral constituents. We hope that the present calculations could be tested by the experimental measurements.
