Iron porphyrin oxidation
WebThe porphyrin C-N breathing mode increases for (FeTPP) 2N+ compared to (FeTPP) 2 C (1370 vs. 1365 cm -1 ); this may reflect increased x donation from the bridging carbon to the iron atom. Coordination of pyridine lowers the frequencies associated with the Fe-X-Fe stretch to 424 and 445 cm -1, respectively, and decreases the Fe-X force constants.
