Abstract
It is shown that measurement of the derivative of the second-order Raman spectrum with respect to wavelength of the scattered light gives information on the Van Hove critical points of the combined two-phonon energy function. The results of such a measurement on SrTiO3 at 10°K are presented and discussed.
