Notes:
Spin-independent alternant systems are analyzed using the alternancy symmetry adapted (ASA) approach. This approach is based on an explicit construction of ASA operators that either commute (altemant) or anticommute (antialternant) with the particle-hole symmetry operator K̂. The method yields an explicit construction and identification of all spin-independent Hamiltonians that describe altemant systems (neutral and/or ionic) as well as an explicit identification of all linear properties characteristic to these systems. It also establishes the connection between the spin-eigenstates and the particle-hole symmetry.
