Laser Light Scattering Studies of Phase Transitions.

Abstract

Very briefly described is research in which the dynamics of phase transition phenomena were investigated by means of laser light scattering spectroscopy. Raman, Brillouin and light-beating techniques were used in exploring the following phenomena: The liquid-vapor critical point in carbon dioxide; The ferroelectric transition in triglycine sulfate (TGS); The alpha-beta structural transition in quartz; The ferroelectric transition in potassium dihydrogen phosphate (KDP) and potassium dideuterium phosphate (KD*P); The order-disorder transition in amonium chloride at high pressure.
