Abstract

Hyperfine structures of the R(58)320, P(55)320, and P(104)340 transitions of molecular iodine near 532 nm are measured by heterodyne beating of two I2-stabilized lasers. The measured hyperfine splittings are fitted to a four-term Hamiltonian, which includes the electric quadrupole, spin–rotation, tensor spin–spin, and scalar spin–spin interactions, with an accuracy of ∼600 Hz for the R(58)320 and P(55)320 transitions. Highly accurate hyperfine constants are obtained from this fit. The rotation dependence of the excited state (the B state, v=32) electric quadrupole constant eQq is found to be eQq(J)=-544.049(14)-0.0002110(43)J(J+1) MHz. The observed hyperfine transitions are good candidates for an optical frequency reference in the 532-nm region.
