The Stretched Vibrations of Carbon Tetrachloride in Alcoholic Environment


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.
