I'm currently studying about the atomic configuration of electrostatic interactions. Concept is there that in case of interactions like in N-H...N-H (amides), the stability depends on the position of resonating electron between H...N nuclei (THE NATURE OF THE CHEMICAL BOND. II. THE ONE-ELECTRON BOND AND THE THREE-ELECTRON BOND - Linus. Pauling).
Given that hydrogen bonds formed between N-H...N-H or N-H...O-C are partial covalent in nature so the issue of directionality comes in effect.
I'm just trying to understand, from the view-point of the electron density shared by H...N to form the bond, that how (if possible) atomic configurations/geometry affects the electron cloud distribution ?
I'm basically trying to understand the hydrogen bond forming amides (currently interested in) from the electronic density distribution's point of view; to calculate the single-point-energy using dft.
