Abstract

Regularities in the Raman spectra of acetate uranyl compounds CsUO2(CH3COO)3, CsUO2(CD3COO)3, NaUO2(CH3COO)3, NaUO2(CD3COO)3, UO2(CH3COO)2, and RbUO2(CH3COO)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 A1) of the uranyl group. The obtained results make it possible to detect and analyze small amounts of uranyl compounds.
