Conjugated electrotopological state

Conjugated electrotopological state [wz03,wfz04b].

Equation 1. Conjugated electrotopological state

Ii is the intrinsic state of atom i () and k the distance influence. The distance influence is reduced by the conjugated topological distance

Equation 2. Conjugated topological distance

where Ci is the conjugated atom i () of the molecule.
