摘要：

The A λmax of protonated Schiff bases derived from retinal, a visual pigment chromophore, experience large bathochromic shifts in a non-polar solvent. The extent of these shifts is dependent on the degree of association between the hydrogen-bonded ion pair formed in the non-polar solvent. The absorptive properties of rhodopsins can be explained in terms of these observations. In addition to bands at ca. 500 and 350 nm, the absorption spectrum for the 11-cisprotonated Schiff base exhibits a minor band at 280 nm. The possible relevance of this band in explaining reported photochemical data of rhodopsins is discussed. © 1968.
