Abstract
A combination of ^19^F nuclear Overhauser effects (NOE) and molecular mechanics calculations are presented for delineating the spatial origin of the well‐known four‐bond ^19^F^19^F COSY connections which are generally observed in the ^19^F NMR spectra of compounds containing perfluorinated chains. Perfluorooctanoic acid (PFOA), R~F~‐palmitic acid‐F~13~ and diethyl perfluorosuberate were used as test cases. Spin–lattice relaxation times (T~1~) are included and NOESY correlations through three and four bonds occur. Copyright © 2005 John Wiley & Sons, Ltd.
