Complexity in real systems

In this section the question of the accuracy of using the effective potential of Eq. (2.26) in dissociation dynamics of a diatomic is studied in the low-friction limit, which corresponds to dissociation in a low-density bath gas. Comparison with experiment will be considered later in this section, but this comparison is difficult because of complexities in real systems, such as adiabatic effects arising from the friction kernel and multiple electronic surfaces. In this...
