was employed for solvent contribution of DMF to the standard Gibbs free energies under the default settings of Gaussian 16 that is widely employed. The internal energies were converted to standard Gibbs energies at 298.15 K using the zero-point energies, thermal correction, and entropy. The electrons and spins were obtained using the natural bond orbital (NBO) technique in the population analysis. 3. RESULT AND DISCUSSION 3.1. Electrochemical analyses of scavenging of O2 •-by RsvH3.
