“…For these reasons, the accurate theoretical calculation of electrode potential has recently attracted considerable attention (see, for example, recent works by Liu-Guo [2,3], Wass [4], Truhlar-Cramer [5][6][7], Houk [8], and Garza [9]). Previously, we have reported the determination of experimental redox potential of some organic and biological compounds using cyclic voltammetry, chronoamperometry and rotating disk electrode voltammetry, together with the theoretical calculation of redox potential using popular quantum mechanical methods [10][11][12]. Very recently, we have also reported accurate calculation of absolute reduction potential of some quinone derivatives in non-aqueous solution of acetonitrile using a high level of theory [13].…”
