A new Cu(II) side-on peroxo model clarifies the assignment of the oxyhemocyanin Raman spectrum
The most intense vibrational feature in the UV rR spectrum of oxyhemocyanin is a band at 267- 296 cm(-1) which has been assigned as either a Cu-Cu stretch or a Cu-N(His)(axial) stretch. Cu(II)(2) side-on peroxo models utilizing bidentate diamine ligand systems retain this vibrational feature, confirming the Cu-Cu stretch assignment. The identity and enhancement behavior of this mode A New Cu(II) Side-on Peroxo Model Clarifies make it an ideal diagnostic of the side-on peroxo Cu2O2 core.
