3]P state is a measure of covalency among other effect which is expressed as Nephelauxetic effect and represented as [[beta].
Consequently, the electrons in both bonds must overlap to some degree, indicating that the electron in the hydrogen bond is circulating around two linked atoms--the hallmark of covalency.
The degree of covalency or ionicity in a bond involving a metal cation is characterised by the Misono softness parameter derived from their ionisation and ionic potentials (see Rengasamy and Sumner 1998, for more details).
