Shape of cf3 radical
WebbIn this case, quantum mechanical calculations find that a set of three s p 2 -hybridized molecular orbitals arising from a D 3 h symmetry has a lower total energy than breaking the symmetry to form the pyramidal C 3 v geometry. However, this does not mean that all C ⋅ X X 3 radicals follow this pattern. http://www.beijingyuji.com/english/innovation/science-are-around/400.html
