Probe Raman spectroscopy of uranyl-compound polycrystals

Regularities in the Raman spectra of acetate uranyl compounds CsUO$_{2}$(CH$_{3}$COO)$_{3}$, CsUO$_{2}$(CD$_{3}$COO)$_{3}$, NaUO$_{2}$(CH$_{3}$COO)$_{3}$, NaUO$_{2}$(CD$_{3}$COO)$_{3}$, UO$_{2}$(CH$_{3}$COO)$_{2}$ и RbUO$_{2}$(CH$_{3}$COO)$_{3}$ have been analyzed. The Raman spectra are excited by 785-nm laser radiation and recorded using a miniature fiber-optic spectrometer with a multielement detector. It is established that the spectra of all these compounds contain a strong Raman satellite with a frequency in the range of 850–860 cm$^{-1}$. This satellite corresponds to symmetric stretching vibrations (type $A_1$) of the uranyl group. The obtained results make it possible to detect and analyze small amounts of uranyl compounds.
