The x-ray absorption near edge structure (XANES) spectra of hemoglobin and myoglobin have been measured at the wiggler beam line of the Frascati Synchrotron Radiation Facility. The energy shifts of the iron absorption jump edge and the chemical shifts of the bound excited state at threshold of 1s core excitations, going from deoxygenated to oxygenated form, are interpreted as evidence of some increase of the positive effective charge on the iron atom upon oxygenation.
血红蛋白和肌红蛋白的X射线吸收近边结构（XANES）光谱已在弗拉斯卡蒂同步辐射装置的摆动器光束线上进行了测量。从脱氧形式转变为氧合形式时，铁吸收跃迁边的能量位移以及1s芯激发阈值处束缚激发态的化学位移，被解释为氧合时铁原子上正有效电荷有所增加的证据。
