| 摘 要： | 利用太赫兹时域光谱技术对六种常用非极性有机溶剂进行了测量,其中包括正己烷、环己烷、石油醚、甲苯、四氯化碳和二硫化碳.由于这些非极性有机溶剂常用于溶解其他有机物,因此测量非极性有机溶剂的光学参数,有助于进一步研究其他有机物在太赫兹波段的各种特性.在提取有机溶剂光学参数的过程中,考虑了用于盛放液体的比色皿对太赫兹信号的影响...

| Abstract: | Six kinds of non-polar organic solvents were measured by using terahertz time-domain spectroscopy(THz-TDS),including positive hexane,cyclohexane,petroleum ether,carbon tetrachloride,carbon bisulfide,and toluene.These non-polar organic solvents are often used to solve other organics,so knowing the parameters of these non-polar organic solvents are important for studying optical properties of other organics in the frequency range of terahertz.The influence of the cuvette on THz signal was considered.Accurate ... |
