Let us consider the article by . These researchers tell that, "Best of all, the complex shape of the obtained spectra was approximated by four (or five) Gaussian-shaped peaks with their positions ) cm -1 . The most intensive constituents were 3230 and 3440 cm -1 lines, their total contribution to the Raman spectrum of water is higher than 90%" . The investigated Raman spectra were those of distilled water. "It is well known that Raman spectra of water have a complex structure . Typical obtained Raman spectra of water are presented in Figs. and [of the article by ." In the Figure , we can find five Gaussian functions, whereas, in the Figure , the Gaussians are four. "It is clearly seen that with great precision the complex spectrum shape may be approximated by four or five Gaussianshaped constituents: two main and two or three minor ones. Positions of maxima for these five constituents are close to 3070, 3230, 3440, 3600 and 3650 cm -1 . The most intense constituents are 3230 and 3440 cm -1 lines that contribute more than 90% to the Raman spectrum of water" .
