We report measurements of the absolute energies of the hyperfine components of the 12s 2S1/2 and 13s 2S1/2 levels of atomic cesium, 133Cs. Using the frequency difference between these components, we determine the hyperfine coupling constants for these states, and report these values with a relative uncertainty of ∼0.06 %. We also examine the hyperfine structure of the 11d 2DJ (J=3/2, 5/2) states, and resolve the sign ambiguity of the hyperfine coupling constants from previous measurements of these states. We also derive new, high precision values for the state energies of the 12s 2S1/2, 13s 2S1/2 and 11d 2DJ states of cesium.
