Szigeti charge

Szigeti charge does not represent the deviation of ihe nature of the bonds from purely ionic, which is the startii point in the Born theory, but the influence of the approximations made in this theory. [Pg.28]

These effective charges were introduced by Szigeti to obtain agreement between the theoretical and the experimental relationships between the characteristic frequencies of the vibrations of the atoms in the lattice and the permittivity [12, 13]. [Pg.27]

The effective charges of atoms in crystals, rather than molecules, can be determined by Szigeti s spectroscopic method [55], which is also described in details in Chap. 11, using the formula... [Pg.60]
