List of free radical scavengers
WebFree radicals are termed spin doubletsbecause of the existence of these two discrete states. In the same way, chemical species with two unpaired electrons are called triplets, since there are three distinguishable spin states of such a system. Species with all electrons paired have only one spin state and are termed singlets. http://research.cm.utexas.edu/nbauld/unit5_radicals.htm
