XX.C.1.a.

Calculated Energies of Hydrogen-Bonded dimers

Dimer Name H Donor H Acceptor comment
CH3OHH2O methanol water dimer CH3OH H2O
Energies in hartrees
Click on entry for more information.
The energies in each cell in the following tables are:
uncorrected 
cp correcteddiff
cp geometry optimzeddiff
The first entry is the calculated energy.
The second entry is the counterpoise corrected energy.
The third entry is the energy from the counterpoise corrected optimized geomtery.
Differences from the uncorrected energy are shown to the right in millihartrees.
