摘　　要：本文发展了测量散射体温度的拉曼光谱方法 ,选用Sr(NO3 ) 2 粉晶做散射介质 ,观测到 738cm-1和10 5 7cm-1两个拉曼散射带 ,记录它们的Stokes和Anti Stokes分量的光谱强度 ,得到硝酸锶粉晶散射体的温度。实验结果显示 ,这种非接触光谱测温法具有重要的实用价值。We have developed a new method for the determination of temperature with Raman scattering spectra.The strontium nitrate was chosen as an experiment substance.It has two bands of Raman scattering,and their wavenumbers are 738 and 1 057 cm -1 in 600—1 700 cm -1 .We have obtained the intensities of their Stokes and Anti Stokes scattering,then we have got two temperatures of strontium nitrate according to the formula.The result from the 738 cm -1 scattering band has larger error than that from the 1 057 cm -1 .This may account for the noise of the photocounter.This no touch method is fit to measure the temperature of the molecular.
