[The measurement of temperature with Raman scattering spectra of polycrystal (SrNO3)2].


PMID 12953490

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.
