The model developed recently by us for calculating the optical properties of a small isotropic sphere, with a radially uniaxial coating of molecules, is extended here to include multicomponent coatings in an approximation in which the molecules, trea

In parts I and II of this series, the dominant role of ‘‘primary’’ Raman moments of degree greater than one, to Raman intensities for molecules forming a uniform coating on pairs of spherical particles in close proximity, is demonstrated. In

In part I, a mathematical formalism was developed for calculating Raman scattering intensities from a collection of spherical particles uniformly coated with molecules, and applied to the special case of two CO‐coated Ag particles in contact, with

The methods developed in our earlier papers, dealing with Raman scattering from small isolated, spherical particles, uniformly coated with radially uniaxial molecules, are extended to include scattering driven by applied multipolar fields. Such field

A differential equation for the polarizability of a small, continuum, spherically symmetric medium is developed in the local‐dielectric‐response approximation. The dynamic polarizability of a small metal sphere is then calculated through this equ
