Anisotropy of the Oxygen K_α X‐Ray Emission Band From Mg(OH)₂, Single Crystals

Abstract

The 30-and 1% molecular orbital contributions to the Oxygen Ko( emission band of the hydroxyl ion can be separated by making use of the fact that, in the Mg(0H) structure, all OH dipoles are oriented parallel to the c-axis. The 02K& component due with a Ill-+ Is transition at 525.5 eV has its maximum intensity parallel to the crystallographic c-direction COO11 , while the 3 4 -1 s component is emitted mainly in the zone (hkO), normal to the c-direction. The 3 4 + 1 s component appears to be split due to electron-proton interaction, exhibiting two maxima at 524.7 and 526.0 eV.
