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.
