Combined theoretical and experimental studies of He I photoelectron spectra for photoionization of the X^1Σ^+ (v″ = 0) ground state HF leading to the X^2Π (v^+ = 0–2) and A ^2Σ^+ (v^+ = 0–3) ionic states, including detailed analyses of the rotational bandshapes, are reported. Agreement between the measured bandshapes and the calculated spectra, convoluted with the experimental resolution function (22 meV FWHM), is excellent. Ionization potentials of 16.046(1) eV and 19.116(2) eV are obtained for formation of the X and A ionic states, respectively. The vibrational spacings, deduced from the measured data by careful bandshape analysis, are in very good agreement with spectroscopic values.
