SF₆ Negative Ion Formation in Charge Transfer Experiments.

ABSTRACT: In the present work, we report an update and extension of the previous ion-pair formation study of Hubers, M.M.; Los, J. Chem. Phys.1975, 10, 235-259, noting new fragment anions from time-of-flight mass spectrometry. The branching ratios obtained from the negative ions formed in K + SF₆ collisions, in a wide energy range from 10.7 up to 213.1 eV in the centre-of-mass frame, show that the main anion is assigned to SF₅^- and contributing to more than 70% of the total ion yield, followed by the non-dissociated parent anion SF₆^- and F^-. Other less intense anions amounting to <20% are assigned to SF₃^- and F₂^-, while a trace contribution at 32u is tentatively assigned
