摘要
探讨了紫外吸收温差谱的形成,谱线加宽可能是其成因之一,不同的物质在不同的温度范围内其主导因素可能各异。分析了温度对多种谱线加宽的影响,并对多普勒效应致温差谱函数进行了理论推导。对于温差谱具有峰位不变和负峰等特征的一类物质,比如C6 0 和黄体酮等,得出的结果可对其给出很好解释,多普勒效应可能是这类物质紫外吸收温差谱形成的主要因素。
In this paper, the formation of UV absorption spectrum from difference in temperature (UVASDT) is discussed. Broadening of spectral lines might be one of the reasons for the fort-nation of UVASDT. The effect of temperature on the broadening of spectral lines is analyzed. The Doppler SDT function is deduced, and the SDT of C-60 and progesterone can be explained by it. It is indicated that the Doppler effect might be the primary reason for the formation of UVASDT of this kind of substance.
