A Cs referenced optical frequency comb system has been used to measure the center frequency of the 5s {sup 2}S{sub 1/2}-4d {sup 2}D{sub 5/2} transition at 445 THz in a single, trapped, and laser-cooled {sup 88}Sr{sup +} ion. The transition frequency {nu}{sub SD}=444 779 044 095 510 Hz{+-}50 Hz (1{sigma}) is obtained, when corrected for systematic shifts. A detailed calculation of the estimated systematic shifts is presented which yields improved values for the various shift parameters including blackbody and electric quadrupole moment shifts.
