chemiluminescence
- n luminescence resulting from a chemical reaction as the oxidation of luciferin in fireflies
- The magnesium or zinc salts of porphyrins also exhibit chemiluminescence when heated in the same manner.
- Speaker was Edmund Newton Harvey, professor of physiology at Princeton and authority on chemiluminescence for the National Research Council.
- He studied chemical reactions by analyzing the faint infrared light emitted when molecules link up to form new substances, a phenomenon known as chemiluminescence.
