摘要: Abstract The ground-state and excited-state dipole moments of fluorescein were studied at room temperature in n -alcohols (methanol– -hexanol) acetonitrile acetonitrile–benzene solvent mixtures. estimated from Lippert's, Bakhshiev's Chamma–Viallet's equations by using the variation Stokes' shift with dielectric constant refractive index. Experimental for -alcohols, mixtures Guggenheim–Smith method (GSM). It was determined that higher than those while they lower solute–solvent interactions on are discussed.
