We perform two-photon photoassociation spectroscopy of the heteronuclear CsYb molecule to measure the binding energies of near-threshold vibrational levels of the $X{\phantom{\rule{3.33333pt}{0ex}}}^{2}{\mathrm{\ensuremath{\Sigma}}}_{1/2}^{+}$ molecular ground state. We report results for $^{133}\mathrm{Cs}^{170}\mathrm{Yb}$, $^{133}\mathrm{Cs}^{173}\mathrm{Yb}$, and $^{133}\mathrm{Cs}^{174}\mathrm{Yb}$, in each case determining the energy of several vibrational levels including the least-bound…
