Abstract


  • Terahertz spectroscopy of benzoic acid (BA) and two of its

    derivatives, 2-hydroxybenzoic acid (2OH-BA) and 3-hydroxybenzoic

    acid (3OH-BA), has been investigated in the spectral region 200

    to 500 cm-1 (6.06 to 15.15 THz). The spectra show distinct

    absorption features. There is agreement between some of the

    absorption lines observed for these compounds, despite a shift in

    energy, which is attributed to the differences in the molecular

    structures. Numerical modelling gave corresponding absorption

    lines, and this helped in the assignment. Temperature dependence

    studies revealed that most of the absorption lines are composite

    lines in this frequency region.
