= Pariser–Parr–Pople method
{wiki=Pariser–Parr–Pople_method}
The Pariser–Parr–Pople (PPP) method is a computational approach in quantum chemistry used for describing the electronic structure of conjugated systems, such as polymers and molecular systems with delocalized π-electrons. The method is particularly suitable for systems where π-conjugation plays a vital role, as it captures the essential physics of electron correlation and the effects of electron-electron interactions in these systems.
