摘要: The ultraviolet absorption spectrum of divalent nickel is shown to be dependent on concentration for crystals composition KMgxNil-xF3 with 0 < x 1. eight bands have intensities which are directly related the number nearest neighbour ions per ion. Three can assigned states 1G and 1S terms while remaining five energies equated combinations excited singlet lEga ITa2g 1Aag simultaneous electronic excitations.
