Abstract In this article, we distinguish the contributions of the positive parity and negative parity $$\Omega _c$$ Ω c states, study the masses and pole residues of the 1S, 1P, 2S and 2P $$\Omega _c$$ Ω c states with the spin $$J=\frac{1}{2}$$ J = 1 2 and $$\frac{3}{2}$$ 3 2 using the QCD sum rules in a consistent way, and we revisit the assignments of the new narrow excited $$\Omega _c^0$$ Ω c 0 states. The predictions support assigning $$\Omega _c(3000)$$ Ω c ( 3000 ) to the 1P $$\Omega _c$$ Ω c state with $$J^P={\frac{1}{2}}^-$$ J P = 1 2 - , assigning $$\Omega _c(3090)$$ Ω c ( 3090 ) to the 1P $$\Omega _c$$ Ω c state with $$J^P={\frac{3}{2}}^-$$ J P = 3 2 - or the 2S $$\Omega _c$$ Ω c state with $$J^P={\frac{1}{2}}^+$$ J P = 1 2 + , and assigning $$\Omega _c(3119)$$ Ω c ( 3119 ) to the 2S $$\Omega _c$$ Ω c state with $$J^P={\frac{3}{2}}^+$$ J P = 3 2 + .
