The aim of this article is to report a unitarily invariant decomposition of arbitrary Hermitian second-order matrices. For the particular cases of antisymmetrical and symmetrical Hermitian second-order matrices this decomposition reduces to the unitarily invariant decompositions of antisymmetrical and symmetrical Hermitian second-order matrices reported by Coleman, A.

Int J Quantum Chem 1984, 25, 1045, respectively. An illustration of physical interest is reported.
