摘要
An application of the topological electron localization function (ELF) analysis to free radical systems is presented. A separation of the ELF function into its alpha-spin and beta-spin contributions has been performed. Methyl and phenyl radicals, ortho-meta-, and para-benzyne biradicals, and their corresponding radical anions have been chosen with the aim to validate the new ELFalpha and ELFbeta proposed functions. The results show that the ELF separation yields complementary information about the localization of the unpaired electron. (C) 2003 Wiley Periodicals, Inc.
