Electron Spin Resonance Studies in Aqueous Solution: Titanium(III) in the pH Region 1.0–3.5

Abstract

In aqueous solutions of titanium(III) between pH 1.0 and 3.5 a single line e.s.r. signal is recorded with g = 1.9408 ± 0.001 and linewidth 95 ± 3 G. Evidence is presented in support of a hydrolyzed metal ion complex [Ti(OH)2(H2O)4]+ as the likely active species.
