The multipoles produced by this analysis are given in their spherical
harmonic definitions. Explicit formulae for translating between the
cartesian and spherical harmonic definitions of the multipole moments
are given in,
*Explicit formulae for the electrostatic energy, forces and torques
between a pair of molecules of arbitrary symmetry*, S. L. Price, A. J. Stone,
and M. Alderton, Molec. Phys., 52, 987 (1984).
