hydrogen bond
in theoretical organic chemistry
A particular type of multicenter (three center - four electron) X–H ...Y in which the central hydrogen atom covalently linked to an electronegative atom X (C, N, O, S..) forms an additional weaker bond with atom Y (N, O, S..) in the direction of its lone electron pair orbital. The energy of hydrogen bonds, which is usually in the range of Math - ei–Math - ei (Math - ei–Math - ei), results from the electrostatic interaction and also from the orbital interaction of the antibonding σ*(XH)MO of the molecule acting as the hydrogen donor and the non-bonding lone electron pair MOnY of the hydrogen acceptor molecule.
