C. Lobo et Jl. Martins, VALENCE FORCE-FIELD MODEL FOR GRAPHENE AND FULLERENES, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 39(2), 1997, pp. 159-164
We present two Valence Force Field models for sp(2) bonded carbon shee
ts with three and five parameters adjusted to the phonon frequencies o
f graphite. The transferability of the force constants is checked for
the vibrations of C-60, where we compare our results to other theoreti
cal and experimental results.
