Solid-state ¹H magic-angle spinning (MAS) NMR was used to investigate local proton environments in anhydrous [UO₂(OH)₂] (α-UOH) and hydrated uranyl hydroxide [(UO₂)₄O(OH₆ 6·5H₂O (metaschoepite). For the metaschoepite material, proton resonances of the μ₂-OH hydroxyl and interlayer waters were resolved, with two-dimensional (2D) double-quantum (DQ) ¹H–¹H NMR correlation experiments revealing strong...
