Hydrogen long-range

Note the relationship between Ha and the other hydrogens. Long-range coupling to Ha (J 4 Hz) is observed in only one of these molecules. Which molecule do you think this is Identify the proton that is coupled to Ha. [Pg.264]

Chemists often call upon certain chemical types of interaction to account for solvent-solvent, solvent-solute, or solute-solute interaction behavior, and we should eon-sider how these ehemical interactions are related to the long-range noncovalent forces discussed above. The important chemical interactions are charge transfer, hydrogen bonding, and the hydrophobic interaction. [Pg.394]

The natural orbitals %2v and %3p are, in contrast to the hydrogenlike functions, localized within approximately the same region around the nucleus as the Is orbital. This means that the polarization caused by the long-range interaction is associated mainly with an angular deformation of the electronic cloud on each atom. If %2p and %3p are expanded in the standard hydrogen-like functions, an appreciable contribution will again come from the continuum. [Pg.282]
