We have investigated the effect of solvent polarity on the conformations of two zwitterions. A Nuclear Magnetic Resonance (NMR) study shows that changing the solvent results in large intramolecular charge transfer. However NMR measurements indicated that a benzenoid ring structure predominates the ground state structure for both zwitterions in polar and non polar solvents. In spite of their very different solvatochromic behaviors, both compounds present a sharp enhancement of the quadratic hyperpolarizability on increasing the solvent polarity.
