Abstract
We report EPR studies on pristine, purified, shortened and soluble SWNTs in various solution phases. Some of these samples give rise to strong, sharp EPR signals, and this technique is useful for monitoring the presence of SW NTs in aqueous and organic solvents. The soluble SWNTs carry about 1 unpair ed electron per 10000 carbon atoms and give a free electron g-value. (C) 19 99 Elsevier Science B.V. All rights reserved.
