Nitrogen charge models

I is the bond length. The experimental quadrupole moment is consistent with a charge, q, of approximately 0.5e. In fact, a better representation of the electrostatic potential around the nitrogen molecule is obtained using the five-charge model shown in Figure 4.20. 

Cracknell et al. [22] proposed a two LJ site and a four-charge model (M = 2 and = 4). The four charges lie on the molecular axis joining the centers of two nitrogen atoms and they are symmetrical with respect to the molecular center of mass. The distance between two positive charges of 0.373e...
