β¦ Synopsis
The hydrogen bond N...H-0 between the water and ammonia molecules has been investigated ab initio using the SCF LCAO MO method. The minimal and extended basis sets of Slater type o:bitak were used. it was found that the energy of the hydrogen bond is equal to 6.44 kcal/mole and the equilibrium separation of the oxygen and nitrogen atoms in the dimer is 5.72 au. At this intermolecular distance there is only one minimum in the potential energy curve for the motion of proton.

The response of a hydrogen-bonded formamide-ammonia complex to an approaching water molecule has been studied by means of ab initio SCF molecular-orbital calculations. Depending on the site of interaction, the major hydrogen bond in the formamide-ammonia system undergoes modifications ranging from s
