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.
