| Abstract: | The 13chemical shifts of simple polymethines (cyanines and merocyanines) show the very pronounced charge alternation in these compounds. The 13C shifts of polar merocyanines are also susceptible to solvent polarity, which in this case has a strong influence upon the electron structure. |
