• Molar heat capacities of RbCl were measured between 3 and 300 K with an adiabatic calorimeter and complete thermodynamic properties of the solids have been obtained. The nature of the lattice vibration spectrum of RbCl is examined in terms of the moments of spectrum. Values derived are θ<SUB>0</SUB>=184.9±1.3 K, θ<SUB>∞</SUB>=190.0±1.0 K, <I>E</I><SUB>z</SUB>(zero-point energy)=3.43±0.01 kJ mol<SUP>−1</SUP>. Those properties depend on the kind of cation rather than on the anion in alkali halides. Anharmonicity in the vibration is also discussed.
