| 摘 要： | We investigate the absorption properties of cyclotrimethylene trinitramine(RDX) single crystals from ～15 to150 cm-1 using the terahertz time-domain spectroscopy. We observe that all the absorption modes exhibit strong anisotropic behavior in terms of the crystal orientations. We demonstrate that the anharmonic phonon model can well describe the temperature-dependent behaviors of these absorption modes. These results indicate that the intermolecular interaction plays a major role in the collectiv...
