摘要: ABSTRACT The visible electronic absorption spectra of two carbanion disubstituted cycloimmonium ylids having a 3-aryl-pyridazinium derivative as cation and common (-2,4,6-picryl-benzoyl) were studied in solvents with different physical chemical properties. band is attributed to an electron charge transfer from the toward heterocycle. solvent effects on described both by empirical parameters defined Kosower using theory dielectric homogeneous solution. Some remarks about nature molecular interactions 3-aryl-phthalazinium-2,4,6-picryl-benzoyl methylid solutions are made this paper basis solvatochromic study.
