Abstract
Crystalline resorcinol [C6H4(OH)2] has been shown to amorphize at 40 k bars, solely using Raman scattering. The external modes vanish resulti ng in a spectrum similar to the density of states spectrum, but the in ternal modes persist indicating a breakdown of translational and orien tational correlation between the molecules. The amorphous state recrys tallizes after the pressure is released. We also provide additional in formation on the known alpha to beta phase transition.
