摘要：

The absorption spectrum of zwitterionic hemicyanine dyes is shifted to the blue and their fluorescence spectrum is shifted to the red by solvents of high polarity. This symmetrical solvatochromism is rationalized by a Born-Marcus-type theory of reversible charging for the positive chromophore alone which is described by an electrical point charge and an electrical point dipole in the center of a sphere.
