Abstract
The relative π-electronic polarizabilities of ideal polymethines are essentially higher than those of comparable aromatic or polyene-like compounds; unsymmetrical merocyanines have the same polarizabilities as polymethines in polar solvents but polarizabilities similar to those of polyenes in non-polar solvents.
