WebIn organic chemistry, polyenes are poly- unsaturated, organic compounds that contain at least three alternating double ( C=C) and single ( C−C) carbon–carbon bonds. These carbon–carbon double bonds interact in a process known as conjugation, resulting in some unusual optical properties. WebChemistry Structure of Dyes: The absorption of electromagnetic radiation by a molecule in the UV and visible regions leads to electronic excitation and an electron moves from a lower to a higher level of electronic energy. The chromophore is known as a covalently unsaturated group which is accountable for the absorption in the visible or UV region.
