Oxidation of luminol by hydrogen per-oxide produces unstable cyclic per-oxide & this on decomposition produces excited triplet 3-aminophthalate first, followed by intersystem crossing to an excited singlet state (forbidden, no emission of light yet). Then the excited singlet state goes to the singlet ground state (allowed) with emission of blue light (λmax = 425 nm). https://www.youtube.com/watch?v=qi9OEPqA9WA | Chemistry Teaching & Learning Video

Explaining Physics on Instagram: "A phenomenon called chemiluminescence, specifically the oxidation of a chemical called luminol. When the two solutions are mixed one containing luminol and a base, and the other an oxidizer like hydrogen peroxide with a catalyst a rapid chemical reaction occurs that boosts electrons into a high-energy "excited" state. The physics behind the glow is governed by quantum mechanics: as these excited electrons inevitably drop back down to their stable ground state, t

Knowledge Adda on Instagram: "Luminol (C₈H₇N₃O₂) is a chemiluminescent compound that emits blue light when it undergoes an oxidation reaction. ✨ When injected into a 10% bleach solution, the sodium hypochlorite (NaOCl) in bleach acts as a strong oxidizing agent, converting luminol into an excited intermediate called 3-aminophthalate. As this intermediate returns to its ground state, it releases energy in the form of visible blue light — a process known as chemiluminescence. This same reaction pr
