| Abstract | ρZ > 0, indicating that the substituent (Z) effects are not transmitted by a direct conjugation. The magnitude of ρZ for Y=NH is the largest among the heteroaromatic systems, which is consistent with the largest transmission efficiency change (ΔS). The equilibria for the addition processes are favorable in the gas phase ( ΔG o 0) due to the relatively large solvation energy of OH - in the initial state in aqueous solution. The orders of ΔG o and ρZ in the gas phase are almost maintained in solution. |
