摘要：

Novel carbon clusters isolated in the solid phase have been characterized by electron ionization (EI) mass spectrometry. The crystalline material contains the C60 and C70 molecules in a ratio of 37:1. Both of these molecules form singly charged ions that appear at m/z 720 and 840, respectively, and doubly charged ions that appear at m/z 360 and 420, respectively. Only the C60 molecule produces the triply charged species, at m/z 240. C60 undergoes fragmentation by losing successive multiples of C2 through C-16. The C70 molecule only loses the fragments C2 and C4. Collisionally activated decomposition of these molecules in the first field-free region did not reveal any more extensive fragmentation than was observed under EI conditions.
