The J=0←1 fine-structure transition in the atomic ion F+ in its ground 3P state has been detected in the laboratory by far-infrared laser magnetic resonance. The fine-structure interval has been measured accurately as 4453253.2±1.6MHz (148.544537±0.000053cm-1) which corresponds to a wavelength of 67.319877±0.000015μm. The hyperfine splitting for the 19F nucleus was also observed and its measured value is in fair agreement with predictions based on ab initio wave functions.
