本文对历史绘画中广泛使用的40种不同颜色的无机颜料在低波数光谱范围（550- 230 cm-1）内的ATR-FT-IR光谱进行了综合研究。用红外光谱法测定了色素与亚麻油的混合物的红外光谱。它表明，该光谱范围-基本上没有常见的粘合剂材料的吸收峰-可以很好地用于鉴定涂料样品中的无机颜料，从而显着地扩展了颜料的识别/确认的可能性，通过ATR-IR光谱到领域的颜料在中红外区域中没有反射。在某些情况下，该方法可以单独用于色素鉴定，在许多情况下，它为使用其他仪器技术（电子探针分析，XRF，光学显微镜）的色素鉴定提供了有用的额外证据。与早期的工作一起，这项研究提供了一个全面的概述，使用ATR-FT-IR的颜料识别的可能性，以及参考光谱的集合，预计将是一个有用的参考保护从业者。
A comprehensive study of ATR-FT-IR spectra of 40 inorganic pigments of different colours widely used in historical paintings has been carried out in the low wave number spectral range (550–230cm−1). The infrared spectra were recorded from mixtures of pigment and linseed oil. It is demonstrated that this spectral range – essentially devoid of absorption peaks of the common binder materials – can be well used for identification of inorganic pigments in paint samples thereby markedly extending the possibilities of pigment identification/confirmation by ATR-IR spectroscopy into the realm of pigments having no absorptions in the mid-IR region. In some cases the method can be used alone for pigment identification and in many cases it provides useful additional evidence for pigment identification using other instrumental techniques (electron microprobe analysis, XRF, optical microscopy). Together with earlier work this study provides a comprehensive overview of the pigment identification possibilities using ATR-FT-IR as well as a collection of reference spectra and is expected to be a useful reference for conservation practitioners.
