For some test systems studied in this work, the discrepancies between the values of firstorder induced dipole moment corrections from propSAPT(DFT) and FF-SAPT(DFT) were observed. These are mainly due to the ALDA approximation of the exchange-correlation kernel used in CPKS calculations, being a part of the propSAPT(DFT) routine. The discrepancies were well visible especially for the CO 2 •••CH 4 in the 'steric' configuration (see Fig. ), CO 2 •••N 2 in the orientation corresponding to min2 (Fig. ) and He•••Ne (Fig. ).
