  • Abstract
    Using the known crystal structure of benzoic acid, the impact of hydrogen disorder on the phonon modes and terahertz spectrum is systematically evaluated using computationally inexpensive rigid molecule atomistic lattice dynamics calculations. The predictions are compared to the measured terahertz spectra.
