On the other hand, Nobumasa Kitajima's dinuclear side-on coordinated peroxo model complexes shows ν(O-O) of 741 cm−1 and UV-Vis absorbances at 349 and 551 nm, which agree with the experimental observations for oxyHc.
Por outra parte, o modelo de Nobumasa Kitajima mostra absorbancias ν(O-O) de 741 cm−1 e UV-Vis a 349 e 551 nm, que concordan coas observacións experimentais da oxihemocianina.
