Response to'Comment on'On the dielectric susceptibility spectra of supercooled o-terphenyl''[J.Chem.Phys.123,154502(2005)]

摘要

In a recent paper,dielectric loss spectra of o-terphenyl(OTP)have been analyzed in order to determine whether time-temperature superposition(TTS)(or frequency-temperature superposition or thermorheological simplicity)holds for OTP in the T_g to 1.2 X T_g range.The motivation for revisiting TTS rests upon the aim of understanding the enhanced self-diffusion in viscous OTP observed by Mapes et al.In order to test the TTS behavior without being biased by particular fit models,common practice has been followed by casting the dielectric loss data into a master plot,where amplitude and frequency position are normalized.
