Conformations of dibucaine and tetracaine in small unilameilar phosphatidylcholine vesicles have been investigated by nuclear Overhauser effects (NOEs) in IH nuclear magnetic resonance spectroscopy. Two-dimensional NOE and chemical exchange correlated spectroscopy (NOESY) and rotating frame NOE spec
## Abstract Twoβto fiveβbond ^15^Nο£Ώ^19^F coupling constants have been determined for fluoropyridines, 8βfluoroquinoline, fluoroanilines and fluoroaniline derivatives. Only in 2βfluoropyridine is __J__(NF) large, and this is associated with a lone pair mediated enhancement of the coupling. Values in
