The X-ray structures of the carboxylic acids, 1-3, have been determined and their bond lengths and bond angles will be compared with those calculated using ab initio methods. Furthermore variations in the HOMO-LUMO gap as well as in the dipole moments of these nonalternate aromatic systems have been calculated and will be discussed.
