The influences of methanol-d₄(MeOD), dimethylsulfoxide-d₆ (Me₂SO(D)) and dioxane(C₄H₈O₂) solvents on the intramolecular processes are studied by NMR. It has been shown that the addition of these solvents in CdEGTA complex aqueous solution can increase the rate constant (k) of the nitrogen inversion and decrease the activation energy of this process. The linear relations between In(k) and the reciprocal of the solvent dielectric constants (1/ε) are obtained for all the three solvents.
