 | | However, infrared spectroscopy has been used successfully for a number of special problems involving painting materials, such as the identification of “copper resinates”1, 2 and organic lake pigments,3, 4, 5 and the characterization of binding media, including varnishes. |
 | | 19 Although very large quantities of most of these were available, all samples were purposely kept small, generally on the order of the size of sample that would often be available from an art object, in order that the quality of spectra that may be expected from such samples is more readily evident. |
 | | Furthermore, the same number of fundamental vibrations would not always necessarily be visible, since degeneracies may be removed to various extents depending upon the precise structure and even the conditions under which the compound crystallized. |
