Abstract

The precision hyperfine structures of the ¹²⁷I ₂ transitions at 561.4 nm are measured by the heterodyne beat between two home-made ¹²⁷I ₂-stabilized Nd:YAG lasers. The theoretical distributions of the observed transitions' hyperfine sublevels are used to identify the two transitions. High-accuracy hyperfine constants are obtained by fitting the measured hyperfine splittings to the four-term Hamiltonian, which includes the electric quadruple, spin-rotation, tensor spin-spin and scalar spin-spin interactions. The absolute frequencies of the observed four transitions are measured by an optical frequency comb based on a mode-locked erbium-fiber laser.
