It should be noted again that within the NEO(MP2)-PNO-LCCSD(T)-F12 the electron-electron correlation is decoupled from the nuclear correlation terms. First of all, we confirm the accuracy of our method for relative energies by comparing Relative energies of the protonated water tetramers with respect to the ring isomer computed with the NEO-PNO-LMP2 (black) and NEO(MP2)-PNO-LCCSD(T) (orange) method shown as dashed lines and their explicitly correlated F12 counterpart as solid lines.
