Lewars" Message-Id: <199908120108.VAA05652@alchemy.chem.utoronto.ca> To: chemistry@ccl.net Subject: RADICAL ANIONS, STABILITY 1999 August 11 RADICAL ANIONS, ELECTRON AFFINITY Calculations on the radical cations of molecules are fairly common, often in connection with comparison with experimental ionization energies. In contrast, little seems to have been published on the experimental or computational study of simple (alkanes, cycloalkanes, etc) radical anions. QUESTION: do simple radical anions, in contrast to radical cations, dissociate spontaneously (e.g. CH3-CH3.- --> CH3. + CH3- )? Has this been well documented experimentally and/or computationally?
