Dear Ari Lahti

  In our Department O. Mo and M. Yanez have made calculation
of hydrogen bonds and related the streghth of the bond with properties of
the bond critical points.

  Have a look at:

   O.Mo,  M. Yanez and J. Elguero
           J. Chem. Phys. 97, 6628 (1992)
           Theochem 314, 73 (1994)

  We have found sometimes problems with gaussian94 when locating the 
critical points because the Hopf-poincare condition was not satisfied, I 
suggest you to use Bader´s programs instead.

  Hope this help
