    • Abstract

       

      IR absorption spectra of BeSO4.4H2O and its deuterated analogue are reported in the region 1200–250 cm−1 at 110 K. The half-widths and relative integrated intensities of the bands are also reported. The study largely confirms the assignments for thev3 andv4 modes of SO42− ion and thev3 mode of Be(aq)42+, complex as made by Diemet al. The assignments of the other modes of SO42− and Be(aq)42+, and the librational modes of water are given a more solid footing as result of the present investigation.
