| 摘 要： | 实验检测了波长为245nm的紫外光激发乙醚-水溶液的荧光光谱。在二阶导数分析的基础上，对乙醚-水溶液的荧光光谱作高斯分解，获得了7条高斯谱线并测定了各自的的中心波长、谱峰强度和半峰宽度。利用高斯基元参数进行了多峰高斯拟合，计算了各高斯谱线对应的基态中最高和最低振动能级差。研究发现，溶液中乙醚分子与水分子以不同的方式结合可以形成7种能发射荧光的缔合分子，其对应的最佳吸收波长不同，引起高斯谱线的半峰宽度各异，中心波长位于304nm的高斯谱线对应的能级差最大。研究结果为乙醚-水溶液中分子缔合结构的进一步研究提供了参考。 |

| Abstract: | The fluorescence spectrum of the ether-water solution excited by the ultraviolet light with the wavelength of 245 nm is experimentally detected.Based on the second derivative analysis,the fluorescence spectrum of the ether-water solution is used as Gaussian decomposition and seven Gaussian spectral lines are obtained.The center wavelength,the peak intensity and the half peak bandwidth of each Gaussian spectral line are measured,and the multi-peak fitting is made by using Gaussian primitive parameters.The hi... |
