| 摘要 | The characteristic absorption features of crystalline benzoic acid in 0.1-4.0 THz have been measured by terahertz time-domain spectroscopy experimentally. Three sharp and low-intensity peaks are observed in the lowest frequency range of 0.1-1.5 THz. In particular, the absorption peak at 0.63 THz is reported for the first time, to the best of our knowledge. Moreover, theoretical simulations have also been performed, and all measured terahertz absorption features are unambiguously assigned. Our calculations clearly show that the first three absorption features arise from translation motions of dimers held together by hydrogen bonds. (C) 2011 Elsevier B.V. All rights reserved. |
