Abstract
Excess of H2O2 reacting in 0.5N HClO4 with Ce4+, Ti3+ and Fe2+ yields the uncomplexed HO2 radical. This radical gives a broad ESR signal with a line width of 27±1 gauss and a g‐value of 2.0140±0.0015. The HO2 radical forms a complex with excess of Ce3+ which gives an ESR spectrum with a linewidth of 1.3±0.1 gauss and a g‐value of 2.0180±0.0005. The equilibrium between complexed [Ce3+‥HO2] and uncomplexed HO2 was studied. Two complexes are formed between HO2 and [Ti4+…H2O2]. These complexes give two ESR signals with a linewidth of 0.7 ± 0.1 and 0.5± 0.1 gauss and g‐value of 2.0140± ± 0.0005 and 2.0120± 0.0005 respectively.
