ResumoThe Raman spectra of uranophane, sodium boltwoodite, soddyite, weeksite, carnotite, and dehydrated schoepite were collected using a microprobe. The dominant feature of all spectra was a strong peak between 738 and 842 cm−1 which was assigned to the symmetric stretch of the uranyl ion. The peak position varies with the environment of the uranyl ion and is helpful in the identification of uranium-bearing phases that form during the water-assisted alteration of high-level nuclear waste.
