An analysis of the 'H and 19F NMR spectra of 2-fluoronaphthalene was performed. 'H-19F inter-ring coupling constants were found to be positive over an even number of intervening bonds between the coupled nuclei and negative over an odd number. Such a sign alternation was based on a positive value fo
