Abstract

We present an accurate and a general model to predict the molar entropy of gaseous diatomic molecule substances. The proposed model is derived from the use of the partition function and shows an excellent agreements with experimental data in a wide range of temperature for CsO, CsF and CsCl molecules. The average relative deviation of the obtained values from experimental data is less than 0.3%.
