Web-based Infrared Spectral Databases Relevant to Conservation
Infrared spectroscopy is one of the most useful analytical methods available to art conservators today. This cost-effective method can be used to identify most organic as well as some inorganic compounds (most binders, fillers, and also some pigments); however, it is impossible to do this without reference spectra. Besides the commercial infrared (IR) spectral databases, there are numerous free infrared spectroscopy resources on the World Wide Web. This paper discusses several of such very good, and freely accessible, IR spectroscopy resources that cover most of the needs of conservators; some of the best-known commercial IR spectral databases are also reviewed. The focus of this paper is mostly on the spectra of traditional materials (mostly pre-20th century artists’ materials). The paper also discusses a number of recent articles that are related to material studies and present various useful spectra for conservation purposes. Many of the sites discussed will be known to experienced infrared spectroscopists, but it is hoped that this paper will be a useful review of reference resources for museum professionals new to the field of infrared spectroscopy.
