Shell-model calculations are presented for ${}_{}{}^{100}{}_{}{}^{}$,102,104Zr for most J values of interest. The theoretical energy spectra for ${}_{}{}^{100}{}_{}{}^{}$,102Zr are in good agreement with the experimental values. The neutron 1$g_{7/2}$ and the proton 1$g_{9/2}$ orbits appear to have a strong correlation in their occupation numbers for all the states.
