摘要: Using different photopyroelectric configurations, we have experimentally studied the frequency dependence of thermal properties glass former glycerol near its transition. With our method, an unambiguous and separate determination specific heat capacity conductivity is possible. Within experimental uncertainty, in range from 0.1 Hz to 1100 Hz, unlike capacity, does not show any through transition region. We also extended spectroscopy 100 kHz, which one decade higher than other methods.
