Raman Spectroscopy of Molten Mixtures of Lithium and Potassium Sulfate

摘要

A broad Raman band at 1100 to 1190 cm exp -1 belonging to nu sub 3 (T sub 2 ) of SO sub 42- in a T/sub d/ symmetry has been observed for Li sub 2 SO sub 4 --K sub 2 SO sub 4 melts. The splitting of nu sub 3 suggests that SO sub 42- experiences a field of lower symmetry, while other features indicate little change in the asymmetry of the environment as Li exp + is replaced by K exp + .
