摘要：

Electronic absorptions leading to predissociation of the HF+ ion are observed by coaxial laser-ion beam photofragment spectroscopy. The absorptions occur in the A2-SIGMA+ <-- X2-product system and terminate in the N = 4, v = 3 level of the A state which predissociates into H+ +F. The (3,4) band of this system is observed for the first time and the observations extend earlier emission measurements in the (3,0) and (3,2) bands to higher rotational levels. In addition, the nuclear hyperfine structure of the ion is observed. Extended molecular constants are derived for the X and A states and the first values are given for the hyperfine structure constants of the A state.
