Absolute frequency of the molecular iodine transition R(56)32-0 near 532 nm

The absolute frequency of the hyperfine component a/sub 10/ in the transition R(56)32-0 of iodine has been measured using the D/sub 2/ line in Rb at 780 mm and an iodine-stabilized 633-nm He-Ne laser as references. This measurement provides a secondary frequency standard within the tuning range of a...

Description
Summary:The absolute frequency of the hyperfine component a/sub 10/ in the transition R(56)32-0 of iodine has been measured using the D/sub 2/ line in Rb at 780 mm and an iodine-stabilized 633-nm He-Ne laser as references. This measurement provides a secondary frequency standard within the tuning range of a doubled Nd:YAG laser. The measured frequency of the a/sub 10/ component is 563 260 223.480 MHz /spl plusmn/70 kHz.< >
