The infrared stretch vibrations (upsilonCO) of the CO-complexes of cytochrome P-450 and cytochrome P-420 have been determined from infrared difference spectra. The CO-complexes exhibit IR-bands at 1949 cm-1 and 1966 cm-1 with half widths of approximately 17 cm-1 and approximately 20 cm-1 respectively. These results are compared with the CO-stretch frequencies of other haemoproteins and discussed with respect to specific interactions of the CO-ligand with the protein moiety and to the ligand trans to CO of the cytochromes.
细胞色素P - 450和细胞色素P - 420的一氧化碳复合物的红外伸缩振动（υCO）已通过红外差示光谱法测定。一氧化碳复合物在1949 cm-1和1966 cm-1处呈现红外吸收带，半高宽分别约为17 cm-1和约20 cm-1。将这些结果与其他血红素蛋白的一氧化碳伸缩频率进行了比较，并就一氧化碳配体与蛋白质部分的特定相互作用以及细胞色素中与一氧化碳处于反位的配体进行了讨论。
