| Abstract: | The dynamic dielectric properties of the title solutions have been measured between 20 MHz and 36 GHz at 20 °C. In addition to spectral components due to the relaxation of solute and solvent as found in similar manner for other binary polar-polar systems, a low frequency feature is observed which is weak for benzophenone but intense for both the derivatives. It can be ascribed to solvent molecules forming a loose salvation shell, where their tumbling motion is slowed down. |
