the adducts arises from the locally excited singlet of the fluorophore, not from charge recombination; (2) rate constants for intramolecular quenching by the nitroxides (ksub q}) are high (10sup 8}-10sup 10} ssup minus}1}) and decrease significantly with increasing nitroxide to fluorophore distance-however, relatively high rates of quenching (>10sup 8} ssup minus}1}) are observed over distances
