Abstract
Lattice frequencies and energies are calculated with an n-6 atom-atom potential to fit recent Raman spectra of solid N2 and neutron scattering data of solid CO2. It is found that n ∞ 9 provides a slightly better fit than the previously used n = 12. The atom-atom potential, giving a fit of about 10% to experimental data, is compared with other potentials and it is pointed out that it can be modified and supplemented by other terms (a quadrupole potential) so as to yield a more realistic potential model, having the expected forms at the limits of large and small intermolecular distance.
