ResumoThe present paper reports the results of an infrared study in the region of the fundamental NH stretching vibration for the twelve N-tert-butylformamide - aromatic hydrocarbon systems. The thermodynamic properties for 1:1 NtBFA - aromatic donor complexes are given. The contribution of the charge transfer mechanism to the hydrogen bonding in the studied systems is considered. The experimental and the calculated intermolecular transition moments are compared and the best agreement is obtained for 2.65 Å hydrogen bond length.
