Abstract
AbstractRegularities in the Raman spectra of acetate uranyl compounds CsUO_2(CH_3COO)_3, CsUO_2(CD_3COO)_3, NaUO_2(CH_3COO)_3, NaUO_2(CD_3COO)_3, UO_2(CH_3COO)_2, and RbUO_2(CH_3COO)_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.
