The q-Gaussians can be used to represent the Kubo lineshapes, so that the q-parameters can be linked to the local environments of the considered dipoles. The value of the q-parameter turns out to the related to the time scale of dynamics (fast q=2, mid q=1.4 and slow q=1). Returning to the O-H stretching band, we could therefore consider that the blue q-Gaussian at about 3250 cm -1 is characterized by a slightly "faster" modulation, that the magenta component. It means that the local environments of the O-H bond, in the blue and magenta cases are different. Further investigation is therefore interesting in the framework of a q-Gaussian approach.
