Abstract
First principles periodic Hartree-Fock calculations of Li:MnO, LixMnO2 and CaMnO3 are reported from which direct evidence is presented to in dicate that the valence state of Mn remains essentially d(5) throughou t the series. The net spin moment on Mn, on the other hand, follows th at convential change from similar to 5 mu(B) to similar to 3 mu(B) ass ociated with the valence states Mn(II), Mn(III), Mn(IV).
