Abstract
Information about 14N relaxation times and (N, F) coupling constants is obtained for three fluoropyridines from (a) a detailed band-shape analysis of the broad 19F resonance bands assigned to ortho-fluorine nuclei, (b) 14N resonance bands, and (c) 15N satellites in 19F resonance. The effects of medium and of temperature were investigated, and activation energies for rotational diffusion are given. Double resonance experiments show that the meta (F, F) coupling constants for 3-chloro-2,4,5,6-tetrafluoropyridine vary in sign.Keywords
