Watch a light-producing chemical reaction while learning about what's happening. Chemiluminescence is when a chemical reaction generates light with little or no heat. When luminol and the other chemiluminescent compounds are produced, they contain excited electrons. When the compounds are reacted with an appropriate oxidizing agent, the electrons relax to a lower energy state, releasing energy in the form of light. Forensic investigators use luminol to detect trace amounts of blood at crime scenes because it reacts with the iron in hemoglobin to produce light. It’s a very powerful forensic tool because it’s capable of detecting bloodstains that were diluted up to 10,000,000 times and it does this without interfering with subsequent DNA testing.
