Minimum magnetizability principle

A softer species is more polarizable" " " and more magnetizable" " . The inverse relationship" " between hardness and polarizability/ magnetizability provides two other electronic structure principles to complement the maximum hardness principle. The minimum polarizability principle" " " (MPP) states that, The natural direction of evolution of any system is towards a state of minimum polarizability and the statement of the minimum magnetizability principle" " (MMP) is, A stable config-uration/conformation of a molecule or a favorable chemical process is associated with a minimum value of the magnetizabihty .
