Density Functional Theory (DFT) calculations show that there is a linear correlation between NICS values (aromaticity criterion) and experimental Hammett (Brown) constants (σp+), together with other computed parameters for p-substituted benzyl cations. © 2001 Elsevier Science Ltd.

Journal of Inorganic and Nuclear Chemistry, 1962
Abstract The first and second stability constants of seventeen copper(II) complexes with aromatic carboxylic acids have been determined at 25° in a 50 per cent by volume water/dioxane solvent with four of these systems being extended to 30 and 35°. The corresponding thermodynamic values have been calculated.

Russian Journal of General Chemistry, 2005
A property-property correlation based on the previously suggested general expression for the quantitative structure-property relationship was obtained; it allows accurate estimation of many properties of organic compounds. Its connection with the Bronsted and Hammett equations was demonstrated.

Linear free energy relationships (LFERs) are an important topic in physical-organic chemistry. When one browses the literature, one encounters innumerable instances wherein the series in question conforms to LFER; one also encounters appreciable numbers of examples of non-conformity to LFER.
