Webbbrations of the Fe-CO bond were not detected with the excitation at 413.1 nm, though the porphyrin Raman lines at 1366 and 674 cm" were clearly observed. When the substrate, … WebbAbstract. Strong evidence suggests that the stretching vibration of the bound oxygen can be perturbed by an accidentally degenerate porphyrin ring mode, resulting in two split frequencies. In the Co (II) (TpivPP) (pyridine) (18)O (2) complex, we demonstrate that the nu ( (18)O- (18)O) mode, after being shifted from its nu ( (16)O- (16)O) value ...
