摘要：

A simple model for ferrous cytochrome P-450 has been investigated by proton and carbon-13 Fourier transform NMR. In the proton spectrum of the β-phenethyl mercaptan-protoheme-CO complex, the protons α and β to mercaptide sulfur are observed 2.62 and 0.62 ppm upfield of tetramethylsilane. The 13CO spectra show characteristic shifts at 204.7 and 197.0 δ for neutral and deprotonated mercaptan complexes, respectively. © 1979.
