A well-known example of an effect involving a persistent and transient one of these molecules is the Barton reaction; that effect was elucidated by Ingold and Fischer.

NBS is used in electrophilic additions and reactions involving these molecules, which can abstract hydrogen. Binding these molecules to the compound DMPO or nitro, nitroso or nitrone functional groups allows them to be analyzed by ESR in a technique known as spin trapping. When drawing reactions involving these molecules, which usually proceed under high temperatures or UV light, one must use fish hook arrows. Reactions using them have three stages: initiation, propagation, and termination. A theory proposed by Denham Harman implicates them in the aging process. These highly reactive chemical species are neutralized by antioxidants. For 10 points, identify this term for atoms or molecules with unpaired electrons.
