21. The five-coordinate CO adducts of hemes exhibited Soret hands at shorter region, ca. 412 nm. than the six-coordinate ones. ca. 420 nm. Thus, the sixth ligand in the present CO complex is concluded to be the thiol. See Reference 2b.
22. Under CO atmosphere, the addition of various bases to ferrous 11 for deprotonation did not yield a hyperporphyrin spectrum, presumably because of the steric and electronic factors of the thiol group.
