We demonstrate a technique for frequency measurements of UV transitions with sub-MHz precision. The frequency is measured using a ring-cavity resonator whose length is calibrated against a reference laser locked to the D<sub>2</sub> line of <sup>87</sup>Rb. We have used this to measure the 398.8 nm <sup>1</sup>S<sub>0</sub> ↔ <sup>1</sup>P<sub>1</sub> line of atomic Yb. We report isotope shifts of all the seven stable isotopes, including the rarest isotope <sup>168</sup>Yb. We have been able to resolve the overlapping <sup>173</sup>Yb (F = 3/2) and <sup>172</sup>Yb transitions for the first time. We also obtain high-precision measurements of the excited-state hyperfine structure in the odd isotopes, <sup>171</sup>Yb and <sup>173</sup>Yb. The measurements resolve several discrepancies among earlier measurements. |
