Figure 3: Temperature dependence of l n 𝐾 S V = l n ( ( 𝜑 0 / 𝜑 1 ) / [ Q ] ) for quenching of 9-cyanoanthracene (1–3) and 1, 12-benzperylene (4) fluorescence by 1, 6-dimethylnaphthalene (1), 1, 4-dimethoxybenzene (2), 1, 3, 5-trimethoxybenzene (3), and 1, 2, 4-trimethoxybenzene (4) in butyronitrile [15]. The line labelled 5 shows the temperature dependence of the diffusion rate constant.
