Luminol Chemiluminescence

概述

Luminol reacts with hydrogen peroxide in the presence of a catalyst (typically iron from hemoglobin in blood) to produce 3-aminophthalate in an excited electronic state. As the molecule relaxes, it emits blue light (425 nm). The iron in blood catalyzes this reaction, making it a powerful forensic tool.
