Two closely related effects based on the nonlinearity of ionic polarizability are considered, ionic Raman scattering and ionic frequency mixing. A simple model is used to make explicit calculations for quartz. Both effects have two resonances associated with each reststrahl band. In addition, antiresonances may occur due to the interference between the ionic process and the corresponding normal process. Although two resonance conditions may be satisfied simultaneously in quartz, the Raman efficiency seems to be below the present limits of observation. On the other hand, the calculation shows that resonant ionic frequency mixing should be observable in quartz.
