The pattern of Mössbauer spectra lines of desoxy- and oxyhemoglobin measured with high accuracy is investigated. The distribution histograms of isomer shifts and quadrupole splittings of spectra components are obtained. An analysis carried out showed a possibility of the approximation of each spectrum pattern by the superposition of two quadrupole splitting doublets with different intensities, similar isomer shifts and quadrupole splittings identical for desoxy- and different for oxyhemoglobin which reflected the difference in nonequivalence of Fe2+ in alpha- and beta-subunits of desoxy- and oxyhemoglobin.
研究了高精度测量的脱氧血红蛋白和氧合血红蛋白的穆斯堡尔谱线模式。得到了光谱成分的同质异能位移和四极分裂的分布直方图。进行的分析表明,每种光谱模式都有可能通过叠加两个具有不同强度、相似同质异能位移且脱氧血红蛋白相同而氧合血红蛋白不同的四极分裂双峰来近似,这反映了脱氧血红蛋白和氧合血红蛋白的α-和β-亚基中Fe2+不等价性的差异。
