Recently, an experimental study of the heat capacity of NdAlO(3) in the 0 to 900 K temperature range by combined low-temperature adiabatic calorimetry and high-temperature drop calorimetry was reported. The two sets of measurements were in good agreement and the enthalpy and entropy for this compound were derived by integration of the heat capacity curve. However, it was not taken into account that the lanthanide compounds often exhibit and excess term to heat capacity and entropy due to the electronic contribution, which will affect the entropy recommendation.
