Consideration of the general effects of size, shape, chemical composition, index of refraction, temperature, and other physical parameters of small particles upon their scattering properties. A determination of the relative importance of these effects to interstellar dust interpretations is attempted with the ultimate aim of a full definition of interstellar grain optics.
