Geometrical substituent parameters for benzene derivatives: inductive and resonance effects☆
TLDR
In this paper, a set of geometrical parameters describing the effect of 21 substituents on the internal angles of the benzene ring has been derived by linear regression from many structural results.About:

Crystallographic studies of inter- and intramolecular interactions reflected in aromatic character of .pi.-electron systems
TL;DR: Application of the HOMA index to benzene rings in various molecular and ionic systems showed that the aromatic character depends rather weakly on deformation from planarity whereas it may be strongly dependent on the intermolecular H-bonding net.
