Abstract

Raman spectra of walpurgite, (UO2)Bi4O4 (AsO4)2·2H2O, recorded at 298 K and 77 K are presented and compared with infrared spectra of walpurgite and phosphowalpurgite. Bands connected with (UO2)2+, (AsO4)3−, and H2O stretch and bend, and Bi[BOND]O stretch are tentatively assigned. Hydrogen bond lengths are calculated from the wavenumbers of the H2O stretching vibrations and compared with those from the crystal structure analysis of walpurgite.
