摘要: The problem of resolving molecular components the electronic structure KH2PO4 single crystal with respect to its chemical and orbital character has been approached by X-ray absorption spectroscopy (XAS) soft emission (SXES). XAS around K-absorption edge O atom was carried out in order existence relation between ferroelectric phase transition. Temperature dependence measured below above TC . Obvious differences at transition temperature were clearly observed. Density states might be gradually changed due local distortion PO4 tetrahedra.
