Mössbauer spectra of eutectic frozen aqueous solutions of Fe(ClO 4 ) 2 have been measured at 4.2 K in applied longitudinal magnetic fields up to 5 T. The spectra are interpreted in terms of a model accounting for the random distribution of the ligand field at the Fe 2+ ion owing to the amorphousness of the environment. The equilibrium state of the Fe(H 2 O) 6 2+ complex is determined by a static Jahn-Teller calculation for T 2g ⊗(ε{lunate} + T 2 ) vibronic coupling the minima of the elastic energy terms being subject to random number generation. The main features of all spectra can be well reproduced by choosing E JT (T) = 140 cm -1 and ω T 150 cm -1 .
