Abstract

We have investigated the photoionization mass spectrometry of clusters of an alkali metal atom (M: Na and K) and methyl vinyl ketone (MVK) or acrolein (AC) to discuss the intracluster oligomerization. In the mass spectra of M(MVK)n, strong ion signals at n=3 are observed. This magic number is explained by the cyclohexane derivative formation in the intracluster oligomerization of MVK initiated by electron transfer from an alkali metal atom. The results of the calculation for Na(MVK) based on density functional theory also show the presence of intracluster electron transfer. On the other hand, in M(AC)n, intensity enhancement is observed at n=4. These intensity enhancements may be due to intracluster reaction in M(AC)n, which is different from the case of M(MVK)n.
