| 摘 要： | 1 Introduction Terahertz time-domain spectroscopy (THz-TDS) is a new spectral technique based on femto-second laser technology developed since the 1980s1]. Terahertz (THz) waves lie between the infrared and microwave bands in the electromagnetic spectrum covering the frequency range from 100 GHz to 10 THz. Despite great scientific interest, the THz frequency range re- mains one of the least tapped regions of the electro- magnetic spectrum because there are neither conven- ient high-power…

| Abstract: | 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. |
