摘要：

Emission and excitation spectra of Cl2 clusters isolated in solid Kr, matrix and free-standing crystal, are reported. A broadened emission progression in the crystal is ascribed to dimeric A' --> X; additional molecular aggregates are evident in the matrix. The dimeric A' state relaxes radiatively with a lifetime identical with that of the monomer (tau = 49 +/- 1 ms), whereas the B state undergoes nonradiative relaxation on a time scale that competes with predissociation. A significant difference in intermolecular binding between excited and ground states is inferred. The clusters do not undergo permanent dissociation at an excess energy of 1.5 eV.
