Recently, it has been shown that the magnetic data for Chromatium ferricytochrome c' at pH 7 are consistent with quantum mechanically (as distinguished from thermally) mixed mid-spin (S = 3/2) and high-spin (S = 5/2) heme. Visible absorption spectra of the protein measured at 77 degrees K and 293 degrees K, pH 7, show peaks at 400, 490, and 632 nm. The observation of a 630 nm band in quantum mixed-spin heme spectra, and the spin state-dependence of the band intensity, are discussed in the context of the iron-ligand structure for quantum mixed-spin heme inferred from magnetic data.
最近有研究表明，在pH值为7时，嗜铬铁细胞色素c'的磁数据与量子力学（与热学相对）混合的中自旋（S = 3/2）和高自旋（S = 5/2）血红素相符。在77 K和293 K、pH值为7的条件下测量的该蛋白质的可见吸收光谱，在400、490和632 nm处显示出峰值。在从磁数据推断出的量子混合自旋血红素的铁配体结构背景下，讨论了量子混合自旋血红素光谱中630 nm波段的观测以及该波段强度的自旋态依赖性。
