Electronic Spectroscopy of CF3O in a Supersonic Jet: Symmetry and Rotational Structure of a Prototypical Perfluoroalkoxy Radical

Article abstract of DOI:10.1021/j100062a005

The <*> <- <*> electronic transition of CF3O was observed in a supersonic yet using laser-induced fluorescence.Rotational analysis of the high-resolution spectrum of the origin band is consistent with CF3O having C_3ν symmetry in both its ground and excited electronic states.The lowest level is best described as ²E_3/2 with residual unquenched electronic angular momentum, leading to a significant spin-orbit splitting.
