Abstract

The rates of bond breaking of the van der Waals bond in the aminotetrazine (AT)-methane, aminomethyltetrazine (AMT)-argon, and dimethyltetrazine (DMT)-argon clusters are measured and compared using fluorescence emission spectroscopy. The results suggest that the rate of breaking of the van der Waals bond depends largely on the cluster density of states and is more or less independent of the cluster geometry. Thus, the rates of bond breaking are quite similar for all three van der Waals clusters even though the AT-methane cluster has a different effective geometry compared to those of the AMT-argon and DMT-argon clusters. The relative rates of AMT-argon and DMT-argon clusters, which have similar geometries, are consistent with the differences in their cluster density of states.
