We report the first driving of the $7s{\phantom{\rule{0.16em}{0ex}}}^{2}{S}_{1/2}\ensuremath{\rightarrow}6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{3/2}$ and $7s{\phantom{\rule{0.16em}{0ex}}}^{2}{S}_{1/2}\ensuremath{\rightarrow}6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{5/2}$ electric quadrupole (E2) transitions in ${\mathrm{Ra}}^{+}$. We measure the frequencies of both E2 transitions and two other low-lying transitions in $^{226}\mathrm{Ra}^{+}$ that are important for controlling the radium ion's motional and internal states: $6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{3/2}\ensuremath{\rightarrow}7p{\phantom{\rule{0.16em}{0ex}}}^{2}{P}_{3/2}^{o}$ and $6d{\phantom{\rule{0.16em}{0ex}}}^{2}{D}_{5/2}\ensuremath{\rightarrow}7p{\phantom{\rule{0.16em}{0ex}}}^{2}{P}_{3/2}^{o}$.
