Abstract

One-bond coupling constants of amino nitrogen in 2-, 3- and 4-nitroanilines have been calculated on the basis of 1H and 13C relaxation times in rotating frame (T1ρ) which are affected by interaction with rapidly relaxing 14N nucleus. A method has been suggested and tested for calculation of 14N-13C couplings with elimination of effects of other relaxation mechanisms. Dependence of 1J(14N13C) on position of nitro group in the aromatic nucleus has been observed.
