We determine the radiative decay amplitudes for the decay into D* and 
, or D
*
s and 
of some of the charmonium-like states classified as X , Y , Z resonances, plus some other hidden charm states which are dynamically generated from the interaction of vector mesons with charm. The mass distributions as a function of the
or
invariant mass show a peculiar behavior as a consequence of the D
*
nature of these states. The experimental search of these magnitudes can shed light on the nature of these states.
