Abstract
Particle populations in nature can often be composed of different chemical components that are either externally or internally mixed. By “external mixture ”, we refer to an ensemble of particles in which different chemical species are contained in physically separated particles; an “internal mixture ” refers to the case in which different chemical components are contained in the same particles. Examples of internal mixtures are liquid-phase aerosols containing water and dissolved sodium chloride. In that case, the two chemical species are homogeneously mixed on the molecular level. Other examples are solid-phase light-absorbing carbon (LAC) aggregates onto which a coating of liquid-phase material has condensed. In the latter case, we are dealing with an inhomogeneous mixture of different chemical species. It is such inhomogeneous particles that will be the focus of this chapter.
