Sample Input Deck for Counterpoise Corrections Using Gaussian 92 or 94 

The first part below calculates the optimum geometry of the water dimer and saves necessary information in a checkpoint file (bsse.chk). The second part, beginning with Link 1 repeats the calculation, but the keyword massage sets the nuclear charge on all atoms in one water molecule equal to zero (atoms 1,3,4). This step should be followed by another calculation that sets the nuclear charge on centers 2, 5, and 6 equal to zero, to obtain the second monomer-corrected term.
