Adiabatic potential energy curves of were calculated by means of pseudopotentialmethod. Very good agreement between the calculated and the experimental curvesallowed for a reliable description of the dissociation process through potentialenergy barriers. The barrier supports several rovibrational quasi-bound states andexplicit time evolution of these states via the time-dependent nuclear Schroedingerequation showed that the state populations decay exponentially in time. We wereable to precisely describe the time-dependent dissociation process of severalrovibrational levels and found that our calculated spectrum match very well withthe assigned experimental spectrum. Moreover, our approach is able to predictthe positions of previously unassigned lines, particularly in the case of theirlow intensity.
