Iron is notable for the range of electronic spin states to which it gives rise. The values of S which are found include every integral and half-integral value from 0 to i.e. every value possible for a d-block element (Table 25.4). 

Hund S rule Atoms in a higher total spin state are more stable than those in a lower spin state. When electrons are added to successive elements to form the periodic table, they fill different orbitals with electrons with the same spin before pairing up. 

In the last example, a serious handicap is the extreme sensitivity of the calculations to the parameterization of the metal atoms. In a paper concerning the spin states of metal dimer complexes (38) as studied by EHT, heavy manipulation of the original theory was needed. In the field of transition metal coordination compounds self-consistent charge (SCC) calculations (of the type already mentioned for electronegative atoms) are essential to obtain the diagonal elements Hu. 

The element is a projector for the first component of the irreducible representation basis. Using standard tableaux functions we can select a function of a given symmetry and a given spin state with...
