Abstract

The hyperfine splitting of the iodine P(119)35-0 transition at 18787.13 cm-1 (532.2793 nm) is measured by heterodyne spectroscopy using two frequency-doubled Nd:YAG lasers. The standard deviation of the theoretical fit to the experimental results is 3.65 kHz. The hyperfine constants for this transition are: electrical quadruple: ΔeQq = 1903.9004 ± 0.07 MHz, spin rotation: ΔC = 114.958 ± 0.047 kHz, scalar spin-spin: Δa = -9.92 ± 4.53 kHz and tensor spin-spin: Δd = -58.86 ± 2.7 kHz. New empirical formulas for the electrical quadruple, spin rotation and tensor spin-spin constants as a function of the vibrational and rotational energies in the B state are derived.
