  • Abstract
    Low-frequency spectra of non-isotopic/deuterated coumarin-3-carboxylic acid under 200 cm-1 was obtained by terahertz (THz) spectroscopy and was compared with calculated harmonic frequencies from DFT calculation with periodic systems to reveal mode assignment of the molecule in THz region.
