Abstract:
On the basis of N(1s) core-level spectroscopic studies, it is found that nitrogen interacts with multimolecular films of C60. More interestingly, mass spectrometric studies show that contact-arc vaporization of graphite in a partial atmosphere of N2 or NH3 yields nitrogenous products tentatively assigned to species such as C70N2, C59N6, C59N4, and C59N2 involving addition of or substitution by nitrogen along with the species due to C2 and C4 losses.
