The measurements of both Stokes shifts and intensities discriminated between protic and aprotic solvents. Fairly good linear correlation plots of the dependence could be obtained on neglection of the values of tert.-butanol, DMF and DMSO.en8-phenylamino-1-naphtalene-sulfonate8,1 ANSaprotic solventprotic solventsolvatochromic fluorescence570610620660530journal article
