| The correlation diagram of eigenenergies versus Planck constant has been proven as a suitable and useful tool for the study of the quantum manifestations of chaos in molecular systems. In this paper, we study the dynamics of the nonlinear LiCN and highly nonlinear KCN molecular systems, showing how the regular classical structures (Kolmogorov-Arnold-Moser tori) embedded in the chaotic sea in phase space (mixed-chaos regime) are manifested in the correlation diagram as emerging diabatic states, which can remain hidden if only a fixed value of the Planck constant is considered (typically h = 1 a.u.). Additionally, the quantum transition from order to chaos is studied, in the framework of the scars frontier reported in the literature, for the two-regions (regular and chaotic) LiCN correlation diagram and for the apparently chaotic (mixed-chaos) KCN correlation diagram, leading to the proposal of a schematic correlation diagram arrangement for a generic molecular system. | |
