Abstract We investigate the geometries and energies of seven electronic states $\tilde {X}$$^{1}\!A_{1}$, $\tilde {A}$$^{1}\!B_{1}$, $\tilde {a}$$^{3}\!B_{1}$, $\tilde {B}$$^{1}\!A_{2}$, $\tilde {b}$$^{3}\!A_{2}$, $\tilde {C}$$^{1}\!B_{2}$ and $\tilde {c}$$^{3}\!B_{2}$ of CF$_{2}$ carbene using internally contracted multireference configuration interaction methods including Davidson correction (icMRCI+Q) with different basis sets aug-cc-pVXZ (X=T, Q, 5). For the first time, the potential energy curves of electronic states of CF$_{2}$ related to the lowest dissociation limit are calculated at the icMRCI+Q/aug-cc-pVTZ level. The ab initio results will further increase our understanding of the structures and dynamics of electronic states of CF$_{2}$ radical.
