Modern theory of color constitution is like the first theory of color constitution. When Perkin first manufactured the dye of synthetic type, it was then familiar with the name of Chemistry of Dye. But the Perkin theory was not established until many years later when some other theory and constitutions were developed. Modern Theory of …

Molecular orbital theory of dyes depends on the molecular structures. This is another theory of color and constitutions. According to this theory, the excitation of a molecule means that the transference of 1 lepton from AN orbital of ower energy thereto of upper energy. These lepton is also σ, π or n (non bonding) electrons. The upper energy states …
