在铁锈样品中发现的铁的氧化物和氢氧化物，产生独特的红外吸收模式，可用于鉴定存在的铁锈相。给出了几种形式的氢氧化物和铁的氧化物的标准红外吸收光谱，用表格编制了数据，并讨论了可用于相鉴别的显著特征。分析了路易斯安那州耐候钢桥跨和2500年前铁斧不同类型锈蚀样品的代表性光谱，并对其特征进行了讨论。在结晶良好的样品中，尖峰变宽，在缺乏结晶度的样品中逐渐变弱。该技术可以有效地用于确定在加热或以其他方式处理信托样品时发生的相变化的性质。
Oxides and oxyhydroxides of iron, found in rust samples, yield distinct infrared absorption patterns which can be used in the identification of rust phases present. Standard IR absorption spectra of several forms of oxyhydroxides and oxides of iron are given, data compiled in tables and salient features that can be used in phase identification are discussed. Representative spectra of different types of rust samples from weathering steel bridge spans in Louisiana and from one 2500 year old iron axe are analysed and discussions of their characteristic features are included. Sharp peaks in well crystallized samples become broad, and progressively weaker, in samples lacking crystallinity. The technique can be used efficiently to determine the nature of phase changes that occur upon heating or otherwise treating trust specimens.
