Ionic Kratzer bond theory and vibrational levels for achiral covalent bond H2Guido Van Hooydonk
Different from the covalent bonding between carbon atoms, the chemical bonds in the BN/AlN systems present both covalent and ionic characters. The lowest-energy structures of B24N24 and Al24N24 are composed of two octagons, sixteen hexagons and eight squares. As for the lowest energy ...
In this review, we have summarized the developments that occurred as a result of the efforts of the Metal Hydride and Chemical Hydrogen Storage Centers of Excellence on materials that bind hydrogen through ionic and covalent linkages and thus could provide moderate temperature, dense phase H2 ...

In NaH A1Σ+ the bond goes from covalent to ionic as υ′ increases: σtotal is very sensitive to an attractive potential due to the interaction of the permanent electric dipole moment of the molecule with the polarizability of the atom (αAr = 11 au, αHe = 1.37 au). The σJi-Jf ...
