CFAC<br />

factor for VWN correlation in ALDA xc-kernel (default 1.d0)<br />

The last threshold values for the 2- and 3-index integrals should not be set higher in density<br />

fitting calculations as this can cause lower accuracies in the interaction terms. In addition SAPT<br />

knows the following subcommands:<br />

MONOMERA<br />

MONOMERB<br />

INTERMOL<br />

Stores informations (like number of electrons, etc.) about previous<br />

monomer A calculation<br />

INTERMOL may have the following subkeywords:<br />

34.1 The property program<br />

The property program allows the evaluation of one-electron operators and expectation values.<br />

Normally, the operators are computed automatically when using the global GEXPEC directive<br />

(see section 6.13) or the EXPEC or TRAN commands in the SCF, MCSCF, and CI programs. The<br />

explicit use of the property program is only necessary in the rare case that the user is interested<br />

in an orbital analysis of the properties.<br />
