Long-range induction coefficients for like centrosymmetric linear molecules and an application to H2–H2

The C8 and C10 long-range induction coefficients for two like centrosymmetric linear molecules are derived explicitly using the irreducible properties of spherical tensor operators. An application to the H2–H2 system shows that whereas the isotropic induction coefficients are 50–100 times smaller than dispersion, the induction anisotropies γn are always larger than the corresponding dispersion anisotropies.
