Indigo Dye Chemical Structure Molecule

Build a molecular model of the Indigo dye chemical structure with genuine Molymod atoms & bonds.

Indigo dye is a naturally occurring compound that has been been extracted from the leaves of plants such as Indigofera tinctoria and Strobilanthes cusia. Indigo pigments have dyed cloth made from silk, wool & cotton for thousands of years. Its chemical structure consists of 6/5 member rings (benzene and pyrrole) connected by a carbonyl group (C=O). The conjugated double bonds (contribute to deep coloration) and aromatic rings form planar structures similar to the DNA nucleotides adenine & guanine. 

The white light spectrum can be refracted by a glass prism into its constituent rainbow of colors. The spectral color Indigo describes wavelengths between blue & violet. The dye Indigo, more properly known as trans-indigotin absorbs light between the wavelengths of 375 to 475 nm with peak absorption at 437 nm.

As far as websites go, Indigo Instruments was the original Indigo going online as indigo.com in 1994.
