Modelling Applications and Theory, Volume

Chemical Modelling Applications and Theory, Volume 1 The Royal Society of Chemistry, 2000 

Section 4 describes specific methods of calculation, with some emphasis on new developments in the period from about 1970 to the present. Section 5 is a literature review of the period 1998-May 1999. 

2 Perturbation of Molecules by Static Electric Fields General Theory 

If the electrostatic potential created at the point, r, by the external field is K(r), the perturbed hamiltonian operator is, 

Traceless forms of the higher multipole operators have been given by Buckingham.12 Much of the work reviewed will refer to the case of a spatially uniform applied field, when the perturbed hamiltonian reduces to
