Relationship between ΔEREDOX and hνCT that has two separate linear correlations in the neutral and ionic regions; the two straight lines intersect when ΔEREDOX ≈ EM, resulting in the hνCT value reaches to the minimum (approximately 0.6 eV). The vertical dashed line indicates the neutral–ionic boundary (Reprinted and modified from Reference26, Copyright 1985, from Taylor & Francis). A: N,N,N’,N’-Tetramethyl-p-phenylenediamine (TMPD)–F4.
