" /> Mulliken population analysis - CISMeF





Preferred Label : Mulliken population analysis;

Detailed label : Mulliken population analysis (MPA);

IUPAC acronym : MPA;

IUPAC definition : A partitioning scheme based on the use of density and overlap matrixes of allocating the electrons of a molecular entity in some fractional manner among its various parts (atoms, bonds, orbitals). As with other schemes of partitioning the electron density in molecules, MPA is arbitrary and strongly dependent on the particular basis set employed. However, comparison of population analyses for a series of molecules is useful for a quantitative description of intra-molecular interactions, chemical reactivity and structural regularities.;
