WebIn the DSEC method, the parameter F of the original scaled external cor- relation (SEC) method68is replaced by a new parameter p, which is unitless and equals 1/F. The general equation for the DSEC energy at a given geometry is EDSEC=ECASSCF+ p(ECASPT2−ECASSCF), (1) where p(unlike F) depends on geometry.
