Abstract

Doppler-free high-resolution spectroscopy is applied to molecular iodine at 532 nm by Nd:YAG lasers. The main hyperfine components as well as the crossover lines are measured for R(56)32-0 and P(54)32-0 transitions by heterodyne beating of two I2-stabilized lasers. The measured hyperfine splittings including both main and crossover lines are fitted to a four-term Hamiltonian, which includes the electric quadrupole, spin–rotation, tensor spin–spin, and scalar spin–spin interactions, with an average deviation of 1 kHz. Absolute values of the electric quadrupole hyperfine constants for both the upper and the lower states are obtained. The rotation dependence of the ground-state (v=0) electric quadrupole constant eQq is found to be eQq(J)=-2452.556(2)-0.000164(5)J(J+1)-0.000000005(2)J2(J+1)2 MHz.

Observed main hyperfine component a10 of the R(56)32-0 transition and the crossover lines nearby. The crossover lines are numbered in series as -1, -2, -3,… if the frequency is lower than that of the a10 component and as 1, 2,… if the frequency is higher than that of a10. Crossover line 2, numbered c9a, is included in the calculation.
