Magnetically induced current density for tetraazaporphyrins (H 2 ATP), phthalocyanine (H 2 Pc), and tetrabenzoporphyrin (H 2 TBP) molecules has been computed. The calculated current strengths for H 2 ATP and H 2 TBP were found to be close to these of free base porphyrin (27 nA/T). The current strengths appeared to have greater value than the same ones for H 2 Pc (21.7 nA/T). The joining of benzene rings to free base porphyrin and to H 2 ATP causes to appear the additional weak ring current densities. The H 2 Pc have a degree of aromaticity less than porphyrins according to magnetic criterion. © 2013 Wiley Periodicals, Inc.
