Abstract
Results of 6Li, 7Li, 23Na, 39K, 85Rb, 87Rb and 133Cs N.M.R. experiments on solutions of the alkali salts of biphenyl and fluorenone in various ethers are presented. The contributions of the Fermi contact interaction and the chemical shielding to the shift of the N.M.R. signal are discussed. Sign and magnitude of the alkali hyperfine splitting constants are derived from the experimentally measured shifts and their variation with temperature and solvent are analysed.Keywords
