WebAny empirical equation which obeys the bond valence sum rule is allowed. Nevertheless, usually only two equations are in use with the bond valence model: R 0, b and N are empirical constants with R 0 as the bond length for a bond with the valence 1. The constants have to be fitted for each pair of atoms.
