The following hypothesis is proposed: When additivity is valid, the molecular frequency distribution (MFD) is a weighted sum of group frequency distributions (GFDs). On the basis of the transformation
A rigorous methodology is developed that addresses numerical and statistical issues when developing group contribution (GC) based property models such as regression methods, optimization algorithms, p
Quantitative structure–property relationships (QSPR) for calculating temperature dependence of surface tension (σ) of ionic liquids (ILs) in terms of group contributions (GCs) is proposed and broadly
A group additivity approach is applied to the large positive heat capacity changes associated with the dissolution process into water of different classes of organic molecules. The results show that t
In this work, the artificial neural network−group contribution (ANN−GC) method has been applied to represent/predict the solubilities of pure chemical compounds in water over the (293 to 298) K temper
