摘要：
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 A(1)) of the uranyl group. The obtained results make it possible to detect and analyze small amounts of uranyl compounds.
