Electric dipole moments of HF–cyclopropane, HF–ethylene, and HF–acetylene have been determined using the molecular beam electric resonance technique. Nuclear quadrupole coupling. 0 0. G. T. Fraser, K. R. Leopold, and W. Klemperer, J. Chem. J. Chem. Internuclear distance. Hydrogen bonding, the third force of attraction two CH 4 O molecules would exhibit, is a special case of It has three polar bonds that are arranged asymmetrically, thus allowing their dipole moments to add up and give the molecule an overall dipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. Dipole moment is not just about charge, it is the product of charge and the bond length.
