Abstract

The hyperfine splitting of molecular iodine R(56) 32-0 transition at 532 nm is measured using a double-passed acousto optic modulator frequency shifting apparatus. Preliminary results, compared with the values recommended by the Consultative Committee for Length, show that the accuracy of our method is better than 20 kHz, which can be easily improved in the future.
