The dynamics of dissociation of clusters induced by multiphoton ionization (MPI) is examined by time-of-flight mass spectrometry with the aid of a reflecting electric field. The systems discussed include ammonia, methanol, xenon, and p-xylene(Ar)/sub n/ clusters. Ammonia and methanol clusters undergo rapid intracluster reactions to yield protonated clusters. Much of the excess energy which leads to dissociation in ammonia, methanol, and xenon clusters results from the energy differences in the ground states of the neutral and ionic systems. On the other hand, in the case of p-xylene(Ar)/sub n/ the energetic differences are much smaller, so that the excess absorbed photon energy may be an important contribution.
