Characterization of Some Orange and Yellow Organic and Fluorescent Pigments by Raman Spectroscopy
Raman spectroscopy has become one of the most important vibrational analytical techniques for the investigation of paint samples and notably for organic pigments. For the analysis of modern materials, especially for synthetic inorganic and organic pigments the prospect of using Raman spectroscopy is an alternative to e.g. Py-GC-MS. It provides enough information allowing for a broad characteriz...
متن کاملCrystal structure prediction of organic pigments: quinacridone as an example
The structures of the alpha, beta and gamma polymorphs of quinacridone (Pigment Violet 19) were predicted using Polymorph Predictor software in combination with X-ray powder diffraction patterns of limited quality. After generation and energy minimization of the possible structures, their powder patterns were compared with the experimental ones. On this basis, candidate structures for the polym...
متن کاملThermodynamic Explanation for the Cosmic Ubiquity of Organic Pigments
There is solid evidence for the occurrence of large amounts of organic material in the cosmos, particularly in the form of aromatic compounds. These molecules can be found on the surface of Earth and Mars, in the atmospheres of the larger planets and on many of their satellites, on asteroids, comets, meteorites, the atmospheres of red giant stars, interstellar nebulae, and in the spiral arms of...
متن کاملIdentification of organic pigments in tattoo inks and permanent
Nowadays, about 12% of the European and 20% of the US population are tattooed. Rising concerns regarding consumer safety, led to legal restrictions on tattoo inks and permanent make-up (PMU) inks. Restrictions also include bans on certain hazardous colourants. Both ink types use organic pigments for colour-giving, plus inorganic pigments for white and black and colour tones. Pigments are only s...
