Using solvatochromic probes to investigate intermolecular interactions in 1,4-dioxane/methanol/acetonitrile solvent mixtures

Kamlet-Taft parameters π*, α and β were also computed for all 40 systems and their variation with composition was thoroughly examined. The addition of small amounts of 1,4-dioxane to the mixtures was seen to cause a significant variation in π*, whereas on the other extreme, in dioxane rich mixtures, a large effect in α was observed, particularly for the system 1,4-dioxane/methanol.
