Abstract
The phase transition temperature in pyrene and phenanthrene crystals has been measured by a polarization modulation method, which enables one to detect the variation in the refractive index in the transparent region of a crystal. The phase transition occurs at 120K in pyrene and between 210 and 260K in phenanthrene.Keywords
