1 H and 19 F nuclear magnetic resonance spectra of some para substituted fluorobenzenes. II

Abstract
The ring proton and fluorine nuclear magnetic resonance spectra of p-fluoronitrobenzene, p-fluorobenzoyl chloride and p-fluorobenzene sulphonyl chloride have been studied as an A2B2X system at 40 and 56·445 Mc/sec. The involved spin coupling constants and chemical shifts are determined.
