Here special problems arise in determining the electron affinity of ionic crystals. These are discussed, together with some of the issues which cause similar problems in different types of systems, here including aqueous solutions and conducting polymers. For ionic solids, knowledge of which charge states are stable for substitutional transition metal ions gives a powerful tool, giving predictions in accordance with electrochemical data. It appears that MgO has a negative electron affinity. date: 1993-09 publisher: ACADEMIC PRESS INC JNL-COMP SUBSCRIPTIONS official_url: http://dx.doi.org/10.1006/jssc.1993.1259 vfaculties: VMPS oa_status: green language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual doi: 10.1006/jssc.1993.1259 language_elements: EN lyricists_name: STONEHAM, ARTHUR lyricists_id: AMSTO63 full_text_status: public publication: Journal of Solid State Chemistry volume: 106 number: 1 pagerange: 2 - 12 issn: 0022-4596 citation: Stoneham, AM; Ramos, MMD; (1993) Equilibria and Electronic Processes.
