(a) THz absorption spectroscopy of terpineol on the basis of DFT; (b) THz absorption spectroscopy of terpineol on the basis of experiment; typical vibration modes at (c) 4.17 THz; black, grey, and red atoms represent carbon, hydrogen, and oxygen atoms, respectively. The blue arrows indicate the vibration direction of atoms, and the length of the arrow indicates the vibration amplitude of atoms.
