Axilrod–Teller Potential

The Axilrod–Teller potential is a three-body potential that results from a third-order perturbation correction to the attractive London dispersion interactions (instantaneous induced dipole-induced dipole)

V_{ijk}= E_{0} left[
frac{1 + 3 cosgamma_{i} cosgamma_{j} cosgamma_{k}}{left( r_{ij} r_{jk} r_{ik} right)^3}

where is the distance between atoms and, and is the angle between the vectors and . The coefficient is positive and of the order, where is the ionization energy and is the mean atomic polarizability; the exact value of depends on the magnitudes of the dipole matrix elements and on the energies of the orbitals.

Famous quotes containing the word potential:

    If the Russians have gone too far in subjecting the child and his peer group to conformity to a single set of values imposed by the adult society, perhaps we have reached the point of diminishing returns in allowing excessive autonomy and in failing to utilize the constructive potential of the peer group in developing social responsibility and consideration for others.
    Urie Bronfenbrenner (b. 1917)
