摘要：

The interaction of the dye safranine T (ST) in the ground and excited states with polyethylene glycols (PEGs) of five different molar masses was studied. The binding parameters of the combinations were estimated in terms of Langmuir and Scatchard equations. The spectroscopic study has enabled the solvent parameters of the aqueous PEG media to be estimated by comparison with such parameters for pure solvents.
