Abstract
Raman spectroscopy is employed to study vibrational and orientational relaxation of sulfite ions in aqueous solutions at temperatures rangin g from 293 to 363 K. It is shown that the basic mechanism of vibration al relaxation is vibrational dephasing. Interaction between cations an d anions reduces the time of vibrational relaxation. Sulfite ion reori entation is shown to occur via hopping diffusion without rupture of io n-molecular hydrogen bonds.
