Abstract:

Hydrogenated carbon cluster ions (C_nH~+_m) were produced by direct laser ablation of solid aromatic compounds and studied with a time-of flight mass spectrometer. In the low mass region (n=32-56), the hydrogenated carbon clusters were obtained with both even and odd carbon atom numbers, while in the high mass region (n>100), the hydrogenated ones were obtained with only even carbon atom number as well as the pure carbon clusters. A structuxal model combining aromatic group and fullerene-like cage for the low mass region and a model combining snail and cylinder types for the high mass region have been suggested.

Key words: Hydrogenated carbon cluster, Laser ablation, Time-of-filight mass spectrometer
