title: Time-resolved EPR observation of synthetic eumelanin-superoxide radical pairs.
abstract: TR-EPR spectra of UV irradiated synthetic eumelanin in equilibrium with air oxygen, reveal the formation of melanin-superoxide radical pairs and allow to determine both the electron dipolar interaction D and the exchange interaction J between the two radicals.
