Fig. 1.11. (cont.) The Si and S2 potential energy surfaces have been calculated by Nonella and Huber (1986) and Suter, Briihlmann, and Huber (1990), respectively, whereas the PES for the So state is approximated by the sum of two uncoupled Morse oscillators. The shaded circles indicate the equilibrium region of the ground electronic state where the dissociative motion in the excited electronic states starts and the heavy arrows illustrate the subsequent dissociation paths. Detailed discussions of the absorption spectra and the vibrational state distributions of NO follow in Chapters 7 and 9. 

Fig. 8.11. (cont.) the unstable periodic orbit, represented by the solid line, influences the dissociation dynamics all direct trajectories, which fragment immediately without any recurrence, are discarded. The times range from 0 fs in (a) to 50.8 fs in (h). The arrows schematically indicate the evolution of the classical wavepacket and the heavy dot marks the equilibrium of the R-state potential energy surface.
