We report on the absolute frequency measurement of the 2S - 3S two-photon transition of lithium-7 and -6 by employing a frequency comb. The values we obtained in this measurement are a factor ten times better than the last reported ones. We also discuss how a detailed description of the line profile is necessary in order improve the measured values.
