We show spectrometrically that H 2 O 2 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 H 2 O 2 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 H 2 O 2 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.
