CH 110K Lecture Notes - Lecture 11: Luminol, Nitro Compound, Chemiluminescence
Document Summary
Synthesizing luminol: luminol is an amid, amides are derivatives of carboxylic acids, start with parent carboxylic acid and a parent amine. Luminol used in crime scene investigations to detect blood: blood mimic potassium feri cyanide, the iron is the same as in blood, this is going to be the oxidizing agent. It was my luminol in the mixture that allowed it to glow in the dark . Usually the electron gets rid of it with the vibrational energy (heat) Sometimes, the energy goes from excited energy state and is released all at once and the electron goes back to the ground state. When it releases all at once, it"s a photon: this is fluresance. Sometimes the electron goes from an excited singlet state to triplet state. These states deal with the spin state pairing of electrons, when they are spin paired (+1/2, Flips its spins: this costs energy, so excited triplet state is lower in energy than excited singlet state.
