The nonstatistical multiphoton ionization-dissociation of the van der Waals toluene dimer

The persistence of van der Waals bimer ions in the fragmentation pattern of the toluene dimer ion can be accounted for by using a simple, physically motivated constraint. The computations predict that many of these bimers are in predissociative states. Comparison is made with the observed patterns of Squire and Bernstein (preceding paper). Uncertainties in the dissociation energies of the bimer ions preclude however a quantitative check.
