Vibrational dephasing of spherical top anions in aqueous solutions

The vibrational dephasing times for spherical top anions in aqueous solutions calculated from in the shape of the isotropic Raman bands of the fully symmetric vibrations of anions, depending on the temperature and the nature of the anion, are analyzed. It is concluded that the dephasing rates for the anions and their temperature dependences can be reasonably explained within the framework of a model that describes the vibrational dephasing of a diatomic molecule interacting with a solvent molecule by using the Morse potential.
