 | | 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. |
 | | 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. |
 | | 62 The strongest bands, at 632 and 566 cm−1 in Cr2O3, do not correspond to specific O2− displacements and are probably due to various combinations of O2− and Cr3+ displacements in the lattice. |
