Abstract: The main aim of this thesis is to determine the HDO Raman spectrum. This spectrum cannot be measured separately in its liquid form, but it is possible to obtain it by a specific mathematical processing of sets of measured spectra with different H/D ratios. In this work we measured Raman spectra of liquid water with different mole fractions of water and heavy water, which were evaluated by factor analysis. Except for well-known spectra of water and heavy water, spectrum of HDO was determined. For fitting of this spectrum and its analysis, model with equilibrium constant and linear correction of the spectral shape with respect to the relative ratio of D was used.
