摘要：
The excimer formation that occurs subsequent to excitation of the naphthalene trimer and tetramer has been probed by mass-selective pump-probe photoionization spectroscopy. The excimer is identified as a strongly bound dimer core, surrounded by ground-state naphthalene molecules. We show direct evidence that these clusters ionize with high efficiency via excimer formation. The ionization enhancement is explained by large Franck-Condon factors for the ionizing transition from the excimer state.
