Easily stored as a solid, iodine is a being considered as a replacement for xenon propellant in electric propulsion systems for spacecraft. One challenge in assessing the performance of iodine-based thrusters has been a of lack spectroscopic schemes for measuring the iodine ion exhaust velocity and flux distribution in the plume. A new laser-induced fluorescence scheme is demonstrated for singly ionized atomic iodine (I II). The hyperfine structure of the D 4 o 5 and P 3 5 states used in the scheme is apparent, and likely values of the magnetic dipole hyperfine coefficients are presented for both electronic states.
