TL;DR: In this paper, the polarized transmission Raman spectra of Ge(As) have been measured for impurity concentrations spanning the Mott transition, and the valley-orbit Raman line broadens markedly at the transition; its line shape has been fitted using the London Heitler method.
Abstract: By use of an yttrium aluminum garnet laser operating at 2.1 \ensuremath{\mu}m, polarized transmission Raman spectra of Ge(As) have been measured for impurity concentrations spanning the Mott transition. The valley-orbit Raman line broadens markedly at the transition; its line shape has been fitted using the London-Heitler method. The spectrum in the metallic regime constitutes the first observation of single-particle scattering from intervalley fluctuations.

TL;DR: Experimental results relating to insulator-metal transition problems in V 2 O 3, VO 2, Ti 4 O 7, and NiS are reviewed in this article, where the controversial nature of the high temperature Mott transition in V O 3 is commented upon.
