Synthesis of highly 13 C isotope enriched azafullerene, C 59 N embedded in C 60 is reported. 13 C enriched fullerenes, produced with the Krätschmer-Huffmann process, were subject to a N 2 discharge that produces C 59 N with a low probability. Raman spectroscopy indicates a homogeneous 13 C distribution. Electron spin resonance measurement (ESR) proves that the C 59 N concentration, 0.2 %, is si...

The intensities of the two strongest low-binding energy features in the valence-band photoemission spectra of C59N have been observed to oscillate as the photon energy of the exciting radiation is varied. The maxima in the intensity ratio of the two peaks occur at the same photon energies as the maxima in the intensity ratios of the highest occupied molecular orbitals to next highest occupied m...

The structural stabilities, geometry and electronic properties of C24 and some its heterofullerenederivatives are compared at the B3LYP/6-311-EFG**//B3LYP/6-31+G* level of theory. Vibrationalfrequency calculations show that all the systems are true minima. The calculated binding energies ofheterofullerenes show C24 as the, most stable fullerenes by 9.03eV/atom. While decreasing bindingenergy in...
