Thermodynamic functions (heat capacity, enthalpy, free energy, and entropy) were recalculated for 7 LiAlF 4 from new spectroscopic data. The calculations were extended to include 6 LiAlF 4 and NaAlF 4 . The calculated entropy value of S 925 0= 110.98 e. u from the data on 7 LiAlF 4 shows excellent agreement with the recently reported thermo dynamic value (110.9 ± 2.5 e. u.). For NaAlF 4 the agreement is not so good, but the calculated value of S 910 0= 113.20 e. u. compares fairly well with the most recent thermo dynamic value (116.8 ± 2.9 e.u.).
