structure–property correlation on the base of Hammett relationships. All of the hydrazone derivatives were found to equilibrate in acetone solution, and more of them existed in one rotameric form in solid state. The aryl substituents influence the intermolecular and intramolecularinteractions differently, because the derivatives could be isolated as two distinct crystals only in a few members. Moreover, the RAHB concept
