Abstract

Abstract: We show spectrometrically that H2 O2 and HO − solvation resolves the H−O stretching vibration from the mode of the ordinary water centered at ∼3200 cm −1 to its below by O:⇔:O compression. An excessive mode due H2 O2 solute appears at ∼ 3550 cm −1 and due HO − at ∼3610 cm −1, which features the effect of molecular solute bond‐order deficiency. The O:⇔:O compression has the same effect to applied pressure that elongates the solvent H−O bond and shortens the O:H nonbond. The H2 O2 is less than the HO − capable of raising the surface stress and transforming the fraction of the H−O bonds because of the involvement of solute‐solute interactions. Abstract : The H−O stretching vibration of HO − and H2 O2 solvation is characterized spectrometrically. Differential Raman spectrometrics enables us to revealed that: (a) HO − and H2 O2 solvation resolves the solute capability of transforming the solution bond, (b) the solute‐solvent O:⇔:O repulsion effects the same to mechanical compression elongating the solvent H−O bond and shortening the O:H nonbond, (c) bond‐order deficiency shortens and stiffens the H−O bond due HO − and H2 O2 solutes, and (d) H2 O2 is less than the HO − capable of transforming the H−O bonds and solution surface stress.
