Abstract

Crystalline resorcinol [C6H4(OH)2] has been shown to amorphize at 40 kbars, solely using Raman scattering. The external modes vanish resulting in a spectrum similar to the density of states spectrum, but the internal modes persist indicating a breakdown of translational and orientational correlation between the molecules. The amorphous state recrystallizes after the pressure is released. We also provide additional information on the known α to β phase transition.
