Porphyrins exhibiting ideal symmetry show depolarization ratios of their Raman-active and D 4h A 1g , B 1g , B 2g A 2g type vibrations which are independent of the wavenumber of the exciting radiation, namely 0.125 for 0.75 for A 1g , and and inΓnite for modes. Symmetry-lowering distortions, which c
