Abstract: We report on measurements of the $5S\text{\ensuremath{-}}6P$ rubidium transition frequencies for rubidium isotopes with an absolute uncertainty of $\ensuremath{\le}20\phantom{\rule{0.28em}{0ex}}\mathrm{kHz}$ for the $5S\ensuremath{\rightarrow}\phantom{\rule{0.16em}{0ex}}6{P}_{3/2}$ transition and better than $20\phantom{\rule{0.28em}{0ex}}\mathrm{MHz}$ for the $5S\ensuremath{\rightarrow}\phantom{\rule{0.16em}{0ex}}6{P}_{1/2}$ transition, achieved by saturated absorption spectroscopy. From the results we derive the hyperfine splitting with an accuracy of $30\phantom{\rule{0.28em}{0ex}}\mathrm{kHz}$ and $450\phantom{\rule{0.28em}{0ex}}\mathrm{kHz}$, respectively. This is an improvement of two orders of magnitude for the $5S\ensuremath{\rightarrow}6{P}_{3/2}$ transition to the current state of the art. We also verify the literature values for the $5S\ensuremath{\rightarrow}\phantom{\rule{0.16em}{0ex}}6{P}_{1/2}$ transition, the isotope shifts, as well as the magnetic dipole constants and the electric quadrupole constants.
