- In this study, we utilize light-cone QCD sum rules at twist-3 accuracy to compute the coupling parameters of the $χ_{c1}(2P)$ state with $D$ and $D^*$ mesons. The analysis reveals that the observed $χ_{c1}(3872)$ meson incorporates significant amounts of both charmonium and molecular components. The interplay between these components highlights the exotic nature of $χ_{c1}(3872)$. Furthermore, implications for a possible mixing between the $χ_{b1}(2P)$ state and a potential $B\bar{B}^*$ molecule is discussed. These findings contribute to the understanding of exotic hadron states and their intricate internal structures.
