where T µ 0f and T µ f 0 are the left and right one-photon transition moments, and ⊥ T µ,K 0f and ⊥ T µK f 0 are the nuclear spin-derivatives of the one-photon dipole transition moments; note the use of the compact notation K γ in place of ĥpso K,γ . The CC response expressions for these transition moment derivatives are promptly derived in analogy with the MCD B term 34,39,40
