Abstract
The absorption coefficient, refractive index and optical fingerprint characteristics were acquired by terahertz time-domain spectroscopy in the range of 0.4~1.5THz of the capsule drug ofloxacin. The results show that ofloxacin had multiple absorption peaks with different intensities within the frequency range, and the absorption coefficient spectrum could be used for the identification of ofloxacin. In the range of 0.4~1.5THz,the absorption spectra of ofloxacin molecules were simulated by Gaussion software. The vibration modes of some absorption peaks in the absorption spectra were analyzed and identified using the density functional theory. At 1.06 and 1.13THz, the experimental results show that the absorption peaks are consistent with the absorption peaks of 1.07 and 1.18THz in the theoretical spectrum, which are caused by the vibrational modes in the molecule ofloxacin.
