spectroscopy in the frequency range 50–4000 cm−1. It is proposed an assignment of the –SO3− group vibrational frequencies as well as of the OH and OD groups (for the internal and external vibrations). The anion site symmetry is C1, but the –SO3− local symmetry estimated by spectroscopic methods is nearly ∼C3V. The concentration dependence of the ν(ОН), ν(ОD), ν(NH) and ν(ND) contours on the content of hydrogen
