We calculate the mass and residue of the newly observed Omega(c) (3000) and Omega(c) (3066) states with quantum numbers J(P) = 1/2(-) and 3/2(-) within QCD sum rules. The calculation is carried out by using the general form for interpolating current for J = 1/2 baryon. Our predictions on masses are in good agreement with the experimental results.
