用傅里叶变换拉曼光谱分析了一个罗马日期陶瓷罐的白色油漆样本，发现白色油漆的一种成分是锐钛矿。这表明锐钛矿的存在，通常被认为是现代（20世纪初或更晚）干预的标志，可以追溯到至少两千年前。对样品的进一步检查，使用扫描电子显微镜，使用能量色散x射线分析仪进行化学分析，x射线衍射和微拉曼光谱，证实了锐钛矿的存在，比例很小（约1.5%）。对拉曼分析中锐钛矿检测灵敏度的初步观察的解释进行了探讨。版权所有©2005 John Wiley & Sons， Ltd
Analysis of a sample of white paint from a ceramic pot of Roman date, using FT-Raman spectroscopy indicated that a component of the white paint was anatase. This suggested that the presence of anatase, usually regarded as an indicator of modern (early twentieth century or later) intervention, could extend back at least two thousand years. Further examination of the sample, using scanning electron microscopy, chemical analysis using an energy-dispersive X-ray analyser, X-ray diffraction and micro-Raman spectroscopy, has confirmed the presence of anatase in small proportions (approximately 1.5%). An explanation for the initial observations relating to the sensitivity of anatase detection in Raman analysis is explored. Copyright © 2005 John Wiley & Sons, Ltd.
