摘要: AB initio molecular orbital calculations have been used to investigate the odd-electron sigma and pi interactions in radicals radical ions. One- three electron bond energies are found be strongly dependent on energy match between interacting orbitals. Odd pi-bonds strong for ions involving first row elements, but weak neutral bonds second elements. The principles deduced from these studies applied some current problems chemistry.
