Electronic-Rotational Coupling in Cl–para-H2 Van der Waals Dimers
Figure 5
Coupled electronic-rotational Cl-H2 energy curves that correlate with the rotational state of H2 shown as functions of the Cl-H2 distance . Spin-orbit effects are included; the horizontal dashed lines indicate the asymptotic energies of the Cl-H2 dimer as for the lower and upper spin-orbit levels of the Cl atom.
