Accurate determination of hyperfine constants of upper level of theP(33) 6-3 transition of molecular iodine using a laser diode emittingaround 633 nm

摘要

We have performed measurements of frequency splittings of thendifferent hyperfine components of the P(33) 6-3 transition of ¹²⁷ⁿI₂ by beat frequency measurements using a laser diodenemitting around 633 nm. The four principal hyperfine constants of thenrovibrational level v"=6, J"=33 of the ground electronic state have beenndeduced
