Terahertz and mid-infrared spectroscopy of benzene-1,2-diol

► Terahertz spectra (8-128 cm−1) and mid-infrared spectra (400-2000 cm−1) of benzene-1,2-diol. ► Solid-state and gaseous-state theory to compute. ► The good terahertz and mid-infrared spectral reproduction of benzene-1,2-diol has been achieved.
