Intensity Normalization of Raman Spectra by Means of Various Internal Standards
 Sláma, Vladislav ; Mojzeš, Peter (advisor) ; Procházka, Marek (referee)
The work deals with the testing of selected inorganic anions as internal standards for intensity normalization of Raman spectra. Using the concentration and temperature series of aqueous solutions of PO4 3- , (CH3)2AsO2 - , NO3 - a SO4 2- , impact of the spectral changes of the standard bands for reliability and accuracy of the intensity calibration was studied. Temperature and concentration series of the anion Raman spectra are then used to test normalization by means of the bands of stretching and deformation vibrations of water molecules. In addition, reliability and robustness of the calibration procedures exploiting different spectral parameters present in the Raman spectra of standards was tested. Results of the study reveal possible sources of artifacts and misinterpretations arising from insufficient understanding of the standard behavior due to changes of the physical and chemical parameters, or due to improper calibration procedure applied.
