We report the first driving of the 7s 2S1/2→6d 2D3/2 and 7s 2S1/2→6d 2D5/2 electric quadrupole (E2) transitions in Ra+. We measure the frequencies of both E2 transitions and two other low-lying transitions in 226Ra+ that are important for controlling the radium ion's motional and internal states: 6d 2D3/2→7p 2Po3/2 and 6d 2D5/2→7p 2Po3/2.
