Abstract: A rationalization of the stereochemical behavior of (1)J(CH) and (2)J(CH) coupling constants, involving nuclei in the vicinity of a carbonyl group were carried out in fluoroacetamide (1), chloroacetamide (2), bromoacetamide (3) and cyanoacetamide (4). (1)J(CH) and (2)J(CH) experimental and theoretically calculated coupling constant together with a qualitative analyses of hyperconjugative interactions through NBO data, showed that observed behavior is mainly due to the hyperconjugative interactions and electrostatic effects.
