Absorption and emission spectra of 9,10-dimethylanthracene in the absence (bottom) and presence (top) of 0.05 M N,N-dimethylaniline. The solvent is a mixture of propyl acetate and butyronitrile of relative dielectric constant εr = 14 (43 wt % butyronitrile). The emissions of the exciplex and the locally excited fluorophore are shaded in red and blue, respectively.
