Chemistry of Colour
Colour has fascinated man ever since he was able to see a coloured object. When Perkin manufactured the fast synthetic dye in 1857, little was known of the chemistry of dyes and about dependence of colour on structure. The principles concerning this relationship emerged over the next two decades. The principles are now fully described using the molecular orbital theory. This book deals with all aspects of the chemistry of colour.
