In this investigation we report H-2, H-1 and F-19 spin-lattice relaxation (SLR) rate experiments performed in undercooled aqueous KF-solutions of concentration c less-than-or-equal-to 12 molal under an external pressure of p less-than-or-equal-to 225 MPa. The relaxation rate curves of the various nuclei are consistently interpreted with a two mode - two site approximation of the dynamic structure of the H-bond network in these ionic solutions. The local arrangement of water molecules coordinated to an F--anion can be obtained from Fluor-19 relaxation rate curves and is found to correspond to an almost linear ion-water configuration. This finding is in accord with predictions from theory and computer simulations and corrects earlier findings from other NMR experiments.
