A temperature‐dependent hydrating structure around SO₄²⁻ investigated from Raman spectroscopy

Abstract

The Raman spectra of H 2 O/D 2 OÀNa 2 SO 4 solutions are measured at temperatures (T) up to 573 K. The hydrating structure of SO 42À is investigated based on the solute-correlated (SC) OD/OH stretch bands obtained by the multivariate curve resolution method. Remaining a nearly constant wavenumber of the main peak with increasing temperature, the SC OD/OH bands are narrowed first due to the reduced relative intensity of the shoulder at 2395

“…The solvation structure in aqueous solution is also an important issue in most subdisciplines of chemistry. Hu et al [6] reported Raman spectroscopic study of the hydration structure of the sulfate anion in this special issue. Gerasimova et al [7] studied the phase transition of hexahydrate fluoride using Raman spectroscopy with H/D exchange.…”
