A typical feature of porphyrins is their ability to form chelate salts with metal cations . As a rule , the reaction of the macrocyclic ligand with the metal salt is a self - consistent bimolecular process with associative activation ...

The dielectric constant has been shown to decrease with increasing salt concentra- tion at all temperatures . Its decrease is less pronounced than in solutions of simple ions . Solute ions very weakly affect the rotational mobility of ...
