WebApr 5, 2024 · I am interesting in chromophore group and dipole approximation. For example, i have a molecule (acetone or any other ketone/enol) which is belongs to some symmetry group. Because of the symmetry this molecule has degenerate energy levels. Now, i need to know the way how to destroy degeneracy. WebVat Dye [A Complete Overview] Vat dye, one of the most important dye class, retains C=O chromophore in structure. This chromophore renders water insolubility. From an aqueous media, dyes are reduced and solubilized. In this state dyes show affinity for fibers. With higher strike rate, exhaustion of vat dye is excellent.
