Chromophoric system
WebTo carry out the circular dichroic studies on compounds transparent in the UV-vis region, a suitable chromophoric system needs to be introduced into the molecule in the immediate vicinity of stereogenic center. In such manner the inherently transparent compounds are transformed into so-called cottonogenic derivatives. WebJan 1, 2015 · An isolated chromophoric system with the visible light absorption oscillator located in a given direction (as exemplified by portions of dyes of different classes such as azo, anthraquinone, etc.) (ii) Dye solubility systems derived from alkyl (R) or substituted alkyl groups (RO-, RS-, RCOO-, RHN-, etc.)
