This contribution to the SQM2024 conference covers the molecular hypothesis for the internal structure of some open and hidden charm states. The use of effective theories that incorporate heavy-quark spin symmetry, combined with unitarization techniques, has provided strong evidences supporting this interpretation. In the heavy-light sector, we discuss the double pole structure of the D*0(2300) and the generation of the D*s0(2317). In the hidden charm sector, we focus on the exotic X(3872) and its heavy-quark partner, the X(4014). Furthermore, we emphasize the benefits of femtoscopic measurements in p + p collisions to establish the nature of these states, as well as the potential role of temperature to discern their internal structure.
