摘　　要：The well-resolved absorption spectra of D-xylose,D-ribose,D-arabinose,D-lyxose and other related substances in the spectral region between 0.3 and 2.0 THz are measured using tera-hertz time-domain spectroscopy(THz-TDS)at 295 K.Comparing the absorption spectra of different chemicals,we can distinguish the samples easily.Thus THz-TDS is demonstrated to be a power and characteristic spectral tool,which is highly sensitive to the minor changes of the molecular structures and can be applied to detect and analyze similar materials.

关 键 词：PENTOSES terahertz time-domain spectroscopy(THz-TDS).
