Abstract
The apomyoglobin complexes of cobalt(II) protoporphyrin IX and cobalt(II) 3,10,17,24-tetrasulphonated phthalocyanine have been prepared and the e.s.r. spectra of their adducts with molecular oxygen recorded and quantitatively evaluated. The results obtained are compared with those from other work. The protein provides appropriate conditions for the oxygenation of cobalt(II) tetrasulphonated phthalocyanme at room temperature, and its influence on the e.s.r. parameters due to the molecular oxygen complex of the prosthetic group is discussed.This publication has 12 references indexed in Scilit:
