Terahertz Spectroscopic Investigation of Nitroaniline Isomers

摘要

We firstly present terahertz (THz) spectra of three isomers of nitroaniline samples (o-nitroaniline, m-nitroaniline and p-nitroaniline) using THz time-domain spectroscopy (THz-TDS). The refractive index and the absorption coefficient of these samples are obtained within 0.2-2.5 THz frequency region. The results show that different nitro anilines have different refractive index and absorption peaks.
