We demonstrate time-dependent polarization transfer from molecular rotation to nuclear spin. The ${\mathrm{H}}^{35}\mathrm{Cl}$ $(v=2,J=1,M=1)$ state is excited with a $1.7\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$ laser pulse, and then dissociated with a delayed $235\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ laser pulse to produce $^{35}\mathrm{Cl}$ atoms. Time-dependent polarizations of both $\mathrm{H}^{35}\mathrm{Cl}$ $(v=2,J=1)$ molecules and $^{35}\mathrm{Cl}(^{2}\mathrm{P}_{3∕2})$ atoms, which vary due to hyperfine quantum beating, are measured. The $^{35}\mathrm{Cl}$ nuclear spin is highly polarized $(⟨{M}_{\mathrm{Cl}}⟩\ensuremath{\approx}1.1)$ at a pump-probe delay of $145\phantom{\rule{0.3em}{0ex}}\mathrm{ns}$. Densities surpassing ${10}^{14}\phantom{\rule{0.3em}{0ex}}{\mathrm{cm}}^{\ensuremath{-}3}$ are achieved. The technique is applicable to many atoms not amenable to optical pumping.
