Since visible light results from outer-shell transitions, IBIL can give information about the nature of chemical bonds in materials. ]]></termNote><termCreatedDate>2026-03-30 20:25:29</termCreatedDate><relation><relationType>UF</relationType><termId>31317487</termId><termName>IBIL</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31304514</termId><termName>ion beam analysis</termName><termType>PT</termType></relation></term>  </Zthes>
