thresholds, as the X(3872) and some XYZ particles can be described in terms of a two-meson molecule. Furthermore, doubly charmed states are also predicted. These new states are near the

D^*D^*

and

D^*D^*_s

thresholds, % Therefore, if the previous XYZ are molecules, then, there should be doubly charmed mesons with

J^P=1^+

around the

D^*D^*

threshold. %For this reason, it is important to evaluate observables related to them. Because of the spin

=1

, they do not decay into

DD

. In this article we compute decays to

DD^*

and radiative decays of doubly charmed meson molecules into

DD_{(s)}γ

. and have spin-parity

J^P=1^+

. Their natural decay modes are

D_{(s)}D^*

,

DD_{(s)}π

and

DD_{(s)}γ

and

D^*D_{(s)}γ

. We evaluate the widths of these states, named here as

R_{cc}(3970)

and

S_{cc}(4100)

, and obtain 44 MeV for the non-strangeness, and 24 MeV for the doubly charm-strange state. Essentially, the decay modes are

DD_{(s)}π

and

DD_{(s)}γ

, being the

Dπ

and

Dγ

emitted by one of the

D^*

meson which forms the molecule.
