通过O-2（O-18（2））和NH3与Fe-II（Por）的薄多孔层的顺序反应制备的氧珠蛋白模型Fe（Por）（NH3）（O-2）与NO（（NO）-N-15）在80-100 K下反应，仅形成低自旋硝酸根络合物Fe（Por）（NH3）（eta（1）-ONO 2），因此意味着过氧亚硝酸根中间体，如果形成，必须经历非常容易的异构化为硝酸根类似物。
The oxy-globin models Fe(Por)(NH3)(O-2), prepared by sequential reactions of O-2 (O-18(2)) and NH3 with thin porous layers of Fe-II(Por), react with NO ((NO)-N-15) at 80-100 K to form only the low-spin nitrato complexes Fe(Por)(NH3)(eta(1)-ONO2), thus implying that peroxynitrite intermediates, if formed, must undergo very facile isomerization to the nitrato analog.
