Its variations are quantitatively connected to the shift of the absorption band due to the charge transfer between the ligand (OH or O 2) and the Fe 3+ ion contained in goethite and/or hematite. For ochres containing both hematite and goethite, the a * co-ordinate linearly increases with ...
Water pollution control is presently one of the major thrust areas of scientific research. While coloured organic compounds generally impart only a minor fraction of the organic load to wastewaters, their colour renders them aesthetically unacceptable. Stringent regulating measures are coaxing industries t...
By using two-colour laser-induced-grating spectroscopy (TC-LIGS), we observed the third-overtone spectrum of the O - H stretch of water vapour at a point in a stoichiometric 0957-0233/8/8/013/img2 - air flame. We also demonstrated the extension of these point measurements to a line im...
