We have carried out concurrent optical frequency measurements of the transitions in 171Yb, and in so doing have determined the frequency separation between the P3 0 (F12 = ) and P3 1 (F32 = ) levels with an uncertainty close to the ppb range. The knowledge of this frequency interval will aid experiments relying on the S P1 0 30 - line in 171Yb and 173Yb without access to highly accurate frequency standards.
