A broader implication of this work is that it adds to the understanding that spin delocalization from a radical to its surroundings need not disappear when standard hybrid functionals with 20-25% exact exchange are employed. This has implications for the description of unpaired spins in other contexts, e.g., polarons in solid-state semiconductors, where (de)localization of charge carriers or other spin defects is sensitive to the fraction of exact exchange. It is sometimes assumed that functionals such as B3LYP or PBE0 will localize a hole, but that assumption has been demonstrated to fail in some cases, as it does for OH(aq).
