Abstract in English
Raman spectra of Carbon Tetrachloride in Methanol solutions were
measured. Spectral lines n1 (symmetric stretch vibrations), n3 (asymmetric
stretch vibrations) of Carbon Tetrachloride were analyzed. The Raman spectra
were fitted using Peak-Fit software applying a sum of Gaussian and Lorentzian
components. Results indicate that, there is a clear difference in the behavior of
peak position and width of the two type of vibrations with varying the
structural composition of the surrounding environment due to varying of the
methanol concentration. On the other hand we found that a similarity in the
dependence of the intensity of spectral lines on the concentration of methanol,
with a high degree of non-linearity.
