As the synthesis of fullerenes commands increasing attention, analysis of these molecules is crucial for the determination of chemical composition and structure. Ionization methods employed for mass spectrometric analysis of fullerenes include electron bombardment, negative chemical ionization, laser desorption, fast atom bombardment, field ionization, and, more recently, electrospray ionization, and these techniques have played a pivotal role in the development of fullerence chemistry. Fast atom bombardment mass spectrometry has not been used extensively, presumably due to the low solubility of the samples in the matrix and the poor quality spectra that have been generated. In an attempt to increase the utility of FAB/MS, the authors have examined the addition of a cosolvent to the preferred matrix material, nitrobenzyl alcohol. Several solvents including chlorobenzene, dichlorobenzene, 1-methylnaphthalene, and 1-phenylnaphthalene have been employed successfully giving marked increases in ion abundance and signal duration.
