摘要: Abstract Dielectric properties of trans -stilbene and p -terphenyl have been studied in the frequency range (1 Hz–1 MHz) at room temperature (300 K). The results dielectric constant loss spectra revealed high quality homogeneity single crystalline phase crystals grown with negligible impurity defect concentrations. electrical modulus clearly shows a low maximum indicating that electronic relaxation processes were presented both crystals. molecular mechanisms also observed trans- stilbene no other secondary
