In this paper a short review is given on micro-Raman spectroscopy
where the particles or the dimensions of scattering systems
under investigation are comparable to the wavelength of the exciting
laser light. If the scattering system has well-defined geometries,
e. g. spheres, cylinders, etc., structural resonances can be observed in inelastical light scattering experiments. These resonances can be explained by the well-known Lorenz-Mie-theory. Examples of such Raman-Mie spectra of solid and liquid microspheres, as well as of fibers, are given. A variety of laser light traps are discussed which allow to study such Raman-Mie spectra experimentally.
