Redistribution of this quantity explains why trifluorocarboxylic acid is stronger than its unsubstituted version.
One method of determining the distribution of this quantity quantum mechanically relies on partitioning it into spherical bains, a method named for Hirshfeld. This quantity is equal to Z minus GAP in a method that is prone to the appearance of excessively high off-diagonal terms in the P-matrix; that method is Mulliken population analysis. Redistribution of this quantity explains why trifluorocarboxylic acid is stronger than its unsubstituted version. This quantity, which is redistributed through bonds in the (*) inductive effect, is often denoted by a lowercase delta with a plus or minus. This quantity is redistributed across a bond in which two substituents have differing electronegativities. For 10 points, name this quantity whose total across an entire molecule is nonzero for ions.
