Chemiluminescence Imaging in combustion experiments helps identify the size and shape of the reaction region when fuel is burned.

Most important is the emission from OH and CH radicals at 307nm and 430nm. An ICCD with short gating and using appropriate filters can takes snapshots of the luminescence of either molecule.
