A discussion of the application of Raman scattering to solid state problems is followed by a description of the experimental technique. A recent experiment is described in which the thickness of the domain wall in the strongly coupled ferroelectric-ferroelastic material gadolinium molybdate is found to be within the limits 0.8–3 µ. The Raman scattering from part of the wall volume is characteristic of the high temperature paraelectric phase.
