Fluorine NMR chemical shifts in d10- and f14-metal fluorides

Journal of Magnetic Resonance (1969), 1971
Abstract The present paper examines the origin of the 19F NMR chemical shift increase in metal fluorides with cation d10- and f14-configurations as compared to isostructural fluorides with a p6- configuration. It was shown that this effect may be explained qualitatively on the basis of the Kondo-Yamashita model.

F14. Febrile myoclonus on EEG; benign or epileptic?

Clinical Neurophysiology, 2018
Introduction Febrile myoclonus is an infrequently seen entity in young children. It is thought to be different from febrile seizures and early childhood myoclonic epilepsy. These are reported to not carry an increased risk for epilepsy. Interictal EEG has been reported to vary from normal to generalized spike and wave discharges. Ictal EEG findings of
