Abstract:

A series of carbon cluster anions with a heteroatom have been generated on a home-made apparatus by laser abalation of appropriate samples. The heteroatom includes boron, aluminum, nitrogen, phosphorus or arsenic which is either a ⅢA or a VA group element. The recorded time-of-flight mass spectra show that stabilities of the cluster anions are affected by the composition of the heteroatom. The ⅢA group heteroatom tends to bind with even sizes of carbon atom and the VA group atom selects odd sizes. The even/odd alternation is attributed to the linear configuration of the cluster anions with the heteroatom at the end of the chain.

Key words: Carbon cluster, Linear chain, Even/odd alternation, Laser abalation Mass Spectrometry
