Abstract
The frequencies of three Doppler-free absorption lines of the I-127(2) mole cule in the vicinity of 730 nm have been measured interferometrically with reference to an iodine-stabilized 633-nm He-Ne laser. These frequencies are important as transfer standards for Doppler-free, two-photon spectroscopy of the 1S-2S transitions in muonium, hydrogen, and deuterium (with the use of frequency tripling to generate the necessary 244-nm radiation). The a(15 ) component of the R(26) 5-13 transition has recently been used as a refere nce line in a high-precision measurement of the muonium 1S-2S frequency int erval. Under the conditions reported, the frequency of this transition was found to be 409 253 981.70 (0.14) MHz, similar to 680 MHz away from the muo nium transition. (C) 2000 Optical Society of America.
