ESP of heteronuclear diatomic molecules (MP2/aVTZ).

q: NBO charge (au), μA: dipole moment (debye), where the subscript A designates the atom to which the dipole direction is pointing from the molecular center. The dipole vectors are along the right direction except the left direction of the three cases of CN, NO and OF (for which the nuclear charge difference between two atoms is only 1).
