| Abstract: | The optical properties of elaidic acid in the THz band were investigated by using THz time-domain spectroscopy(THZ-TDS).The absorption and refractive index spectra in the frequency range from 0.5 to 2.5 THz were obtained at room temperature under nitrogen atmosphere,and the results show that elaidic acid had some characteristic absorption peaks,and the average refractive index of the sample was 1.43.The structure and vibrational frequencies of elaidic acid molecule in the THz range were simulated by the B3L... |
