Radical Stabilization in Dissolved Humates
《Open Journal of Physical Chemistry》2011年第3期55-60,共6页Barbora Bakajová Ray von Wandruszka 
Quinoid entities, in which quinone and hydroquinone groups equilibrate via a semiquinone radical intermediate, are a common structural feature in humic materials. The electron paramagnetic resonance (EPR) signals of t...
