A dense grid of high precision lines in the hyperfine structure of the B-X system of I2 is presented. An actively stabilized etalon, locked to the output of a 3He22Ne laser, which is itself locked to a 129I2 hyperfine resonance, was used to measure the absolute frequency of hyperfine components of nearly 600 lines in the range 571-655 nm. The precision obtained by interpolation methods is 1 MHz. From a calculation of the hyperfine structure, centers-of-gravity of the rotational structure were determined, which were incorporated in fits to the rotational structure of 21 bands in the B-X system.
