To formulate and parameterize an accurate empirical potential energy function for molecular simulations of fluorapatite and hydroxyapatite.
Optimized parameters using quantum-chemical calculations for Coulomb and intramolecular interactions alongside experimental data and molecular dynamics simulations for nonbonded parameters.
Developed both flexible and rigid phosphate models for fluorapatite and a rigid phosphate model for hydroxyapatite.
Reproduced experimental crystal parameters within less than 1% deviation across temperatures from 73 to 1273 K.
Demonstrated excellent agreement between computed and experimental infrared spectra at 300 K using the flexible fluorapatite model.
