Problem 55E
Hemoglobin exists in two predominant forms in our bodies. One form, known as oxyhemoglobin, has O2 bound to the iron and the other, known as deoxyhemoglobin, has a water molecule bound instead. Oxyhemoglobin is a low-spin complex that gives arterial blood its red color, and deoxyhemoglobin is a high-spin complex that gives venous blood its darker color. Explain these observations in terms of crystal field splitting. Would you categorize O2 as a strong- or weak-field ligand?
