... vanished after 30 min, and instead, an absorption peak appeared at 637 nm, suggesting the formation of CO–verdoheme. The 637 nm band disappeared gradu- ally and was replaced by a new broad band ... oxyheme appeared at 540 and 579 nm. Then, a broad band appeared at around 660 nm, and was maximal 9–12 min after initiation of the reaction. The spectral features of the final re...
