Resonance Raman spectra are reported for the 16 O 2 and 18 O 2 adducts of cobalt porphyrin complexes with 3,5‐dichloropyridine (DCP) for three different ‘picket‐fence’ porphyrins. It is shown that the v (O—O) effectively couples with an internal mode of DCP giving rise to complicated spectral patterns. These spectral patterns were carefully analyzed to reveal the inherent wavenumbers of v (O—O) which are shown to vary as expected, given the known relative hydrogen bonding capabilities of the three different superstructured porphyrins.
