Concerning the dissociation rate coefficients, a comparison of the predicted and QCT-generated values is shown in Fig. for T = 2,500 K (test temperature) and 20,000 K (training temperature). Dissociation dynamics are predominantly governed by states closest to the centrifugal barrier since these levels are characterized by higher rate coefficients and tend to dissociate quickly. The dissociation component of the surrogate succeeds in capturing the kinetics of these states accurately. This result is partly attributable to the inclusion of the outer turning points, r o , and the location of the centrifugal barrier in terms of bond length, r max . These variables contribute to capturing the steep peak in the rate coefficients near the dissociation limit. An important note is that, at low temperatures, the reference QCT dissociation rate coefficients for the low-lying states are not converged due to intrinsic limitations in the QCT calculations, and many states have negligibly small values.
