Haldane和Lorrain Smith1发现，羧基血红蛋白对光很敏感，几位研究人员已经证明，其他一氧化碳亚铁化合物也具有这种特性。直到凯林和哈特雷发现过氧化铁和肌红蛋白的氰化物化合物是光敏性的，人们普遍认为一氧化碳化合物在这方面是独一无二的。我们现在已经发现氧合血红蛋白、一氧化氮合球蛋白和乙基异氰基合球蛋白是光敏的，从而表明所有已知的能够与铁结合的配体在性质上是相似的。
Haldane and Lorrain Smith1discovered that carboxyhæmoglobin is sensitive to light, and several workers have shown that this property is shared by other ferrohæm–carbon monoxide compounds. Until Keilin and Hartree2found that the cyanide compounds of ferroperoxidase and myoglobin were light-sensitive, it was generally believed that carbon monoxide compounds were unique in this respect. We have now found that oxyhæmoglobin, nitric oxide hæmoglobin and ethyl isocyanide hæmoglobin are light-sensitive, thus showing that all the known ligands able to combine with ferrohæmoglobin are qualitatively similar.
