摘要

We report the measurement of the terahertz (THz) spectra of 4-aminobenzoic acid by using Fourier transform infrared (FTIR) spectroscopy in the 1.5-19.5 THz. Low frequency intermolecular (or phonon) modes between 0.3 and 2.4 THz were also investigated via THz time-domain spectroscopy. Structure and vibrational frequencies of the sample were calculated through density functional theory(DFT). The calculated results are in agreement with the experimental data. Moreover, we have interpreted observed vibrational frequencies using DFT. Two intermolecular or phonon modes were identified at 1.54 and 2.19 THz.
