We evaluated the individual atom contributions to the second harmonic generation (SHG) coefficients of LiCs2PO4 (LCPO) by introducing the partial response functionals on the basis of first principles calculations. The SHG response of LCPO is dominated by the metal-cation-centered groups CsO6 and LiO4, not by the nonmetal-cation-centered groups PO4 expected from the existing models and theories. The SHG coefficients of LCPO are determined mainly by the occupied orbitals O2p and Cs5p as well as by the unoccupied orbitals Cs5d and Li2p. For the SHG response of a material, the polarizable atomic orbitals of the occupied and the unoccupied states are both important.
