AN INTRODUCTION TO QUANTUM CHEMISTRY
www.msg.chem.iastate.edu• Perturbation theory:MP2, MP4,… – Based on adding successive improvements to both wavefunction and energy – In principle, leads to exact result, but perturbation must be small – Hartree-Fock-based perturbation theory originally due to Moller & Plesset (MP); popularized by Pople and Bartlett (MBPT)
