(a) Real part of ( , ) for coupling obtained by dividing ( , ) by , as a function of for = 0.5 eV, d = 1 nm, = 3.9, and balanced charge distributions at 0 K. The imaginary part essentially vanishes. ( , ) for - is essentially identical except for a 180 degree phase shift. (b) Real part of ( , ) for - coupling obtained under the same conditions. The imaginary part is rotated by 90. ( , ) for - coupling is essentially the complex conjugate of ( , ) for - coupling.
