Mass spectrometric studies of trifluoromethylated fullerenes

Electron ionization. thermal surface ionization. matrix-assisted laser desorption/ionization. electrospray ionization, and electron capture mass spectrometric techniques have been applied to the analysis of mixtures of trifluoromethylated C-60 derivatives. For the first time ionization energy and electron affinity values for some of the molecules under investigation have been reported. These ionization characteristics have allowed to explain the differences in the results obtained by means of different mass spectral techniques. (c) 2005 Elsevier B.V. All rights reserved.
