Assignment of terahertz vibrational mode in sucrose powder by comparing with single-crystalline and computational spectra

摘要

It is necessary to get assignment of spectra originated with specific vibrational mode of organic compounds for the practical or industrial application of terahertz spectroscopy. Terahertz spectra of single crystal and powdered sucrose were measured and compared with computational spectrum. The result shows good agreement, and represents the possibility to assign the origin of peaks in the terahertz spectra.
