Fig. : Deconvolution of the OH-stretching band of water, obtained by means of two q-Gaussian functions (red curves). The green dots are representing the data as given by in . The yellow line is the sum of components. Parameters of the functions are given close the components. Note the different value of the q-parameters, meaning that oscillators are in two different environments. The plot is obtained with Fityk, after defining in it the q-Gaussians (see Appendix for further details).
