【Abstract】 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.更多还原
