THE USE OF HAMMETT CONSTANTS TO UNDERSTAND THE NON-COVALENT BINDING OF AROMATICS [PDF]
Computational and Structural Biotechnology Journal, 2012 Non-covalent interactions of aromatics are important in a wide range of chemical and biological applications. The past two decades have seen numerous reports of arene-arene binding being understood in terms Hammett substituent constants, and similar ...

Determination and structural correlation of pKBH+ for meta- and para- substituted benzamides in sulfuric acid solutions [PDF]
Journal of the Serbian Chemical Society, 2006 The protonation of some meta and para substituted benzamides in sulfuric acid solutions was studied by UV spectroscopy in the 190–350 nm region. Principal component analysis was applied to separate the effect of protonation from the medium effect.
