Abstract

Size dependent stability and intracluster reactions have been investigated by photoionization mass spectrometry for alkali metal atom M (M=Na, K, and Cs)-methyl propiolate (HC=CCOOCH3; MP) clusters. The cluster ions with n=3 were predominantly observed in the M+(MP)n series. This intensity anomaly can be explained by a stable benzene derivative formation in intracluster anionic polymerization reaction induced by electron transfer from the metal. From the measurement of photoionization efficiency curves for Cs(MP)n, two different ionization threshold energies were obtained for Cs(MP)3. These two thresholds are concluded to correspond with the ionization energies of solvation type isomer and reaction product, from the results of quantum chemical calculations.
