DISP, DISP(n.nn)

Although post-SCF hydrogen bonding and dispersion energy contributions are calculated, they are not normally printed.  To print these contributions, add keyword DISP.

If a list of hydrogen bonds is wanted, use DISP(n.nn), where n.nn is the value of the cutoff for printing hydrogen bonds.  If DISP(1.0) is used, all hydrogen bonds with a strength of 1.0 or more kcal.mol-1 will be printed.  This is the common cutoff for hydrogen bonds.
