We report frequency measurements at the rovibronic transition P(42)1-14 (772 nm) and R(114)2-11 (735 nm) from the electronic X-1 Sigma( )(g) -> B-3 Pi( )(0u) transition of the iodine molecule (127)I2 with the help of a frequency comb as a reference. By using Doppler-free saturation spectroscopy a frequency precision in the 7 x 10(-10) region is reached and two iodine cells both operated at 550-600 degrees C are compared.

By using Doppler-free saturation spectroscopy a frequency precision in the 7 x 10(-10) region is reached and two iodine cells both operated at 550-600 degrees C are compared. To relate our results to other measurements, the absolute transition frequency of the hyperfine structure line P(148)1-14 a(1) at 780 nm with an already known transition frequency was also determined.
