We have investigated the decay of $^{85}\mathrm{Kr}^{m}$, $^{85}\mathrm{Kr}^{g}$, $^{85}\mathrm{Sr}^{m}$, and $^{85}\mathrm{Sr}^{g}$ using Ge(Li) spectroscopy and intrinsic Ge Compton-suppression spectroscopy techniques. We observe levels at (${J}^{\ensuremath{\pi}}$ in parentheses) g.s. ($\frac{5}{{2}^{\ensuremath{-}}}$), 151.18 ($\frac{3}{{2}^{\ensuremath{-}}}$), 281.01 ($\frac{1}{{2}^{\ensuremath{-}}}$), 513.998 ($\frac{9}{{2}^{+}}$), 731.79 ($\frac{3}{{2}^{\ensuremath{-}}}$), 868.05 ($\frac{7}{{2}^{\ensuremath{-}}}$), and 921 ($\frac{1}{{2}^{\ensuremath{-}}}$,$\frac{3}{{2}^{\ensuremath{-}}}$) KeV. Our data suggest that the \ensuremath{\sim}880 keV level observed in ($t$,$\ensuremath{\alpha}$) and ($^{3}\mathrm{He}$,$d$) reactions is the known 868-keV level. The ${Q}_{\mathrm{EC}}$ value for the $^{85}\mathrm{Sr}^{m}$ decay is calculated to be 1323\ifmmode\pm\else\textpm\fi{}20 keV from our $\frac{\mathrm{EC}}{{\ensuremath{\beta}}^{+}}$ intensity data. We use the cluster-vibration model to calculate the $^{85}\mathrm{Rb}$ level structure and electromagnetic decay properties. For the latter, we discuss the role of the $M1$ tensor operator.NUCLEAR STRUCTURE Cluster-vibration model, influence of $M1$ tensor term.RADIOACTIVITY $^{85}\mathrm{Kr}$, $^{85}\mathrm{Kr}^{m}$, $^{85}\mathrm{Sr}$, and $^{85}\mathrm{Sr}^{m}$.
